INSTALLATION & START-UP INSTRUCTIONS

GENERAL

This document provides instructions and procedures for installing and starting up the Micronik 200 R7426D controller. No special tools are required for mounting and installation. The user interface and LC display allows accurate and easy parameter setting and output adjustment.

BEFORE INSTALLATION NOTE

Fig. 1. Temperature Controller Visually inspect equipment for shipping damage. Report any damage to the appropriate Honeywell representative. Refer to job drawings for specific installation information and mounting location. Verify the controller will be adequately separated from the main power supply, relays or other equipment which can possibly generate electromagnetic interference. Verify that the ambient temperature and the humidity at the controller will be within the limits of 0.50C (32.122F) and 5 to 95% rh. Use shielded wiring in areas with high EMI. All wiring should be separated from power lines by at least 150mm (6). Do not install controllers near frequency converters or other high frequency sources.

MOUNTING

The controller can be mounted in an electric cabinet or an other suitable enclosure. It is suitable for back panel, DIN rail, wall or front panel mounting with an additional available front panel mounting frame. The mounting sequence of each as well as dimensions and panel cut-out is illustrated in the mounting instruction sheet EN1B-0202GE51 supplied with the controllers. If the compensation sensor signal (T3) is received from another controller (parallel connection of compensation sensor inputs), the jumper W303 must be cut before mounting the controller (see Fig. 2). This disconnects the sensor from the internal power supply.

WIRING

Screwless type, spring loaded terminals are provided on the controllers for wiring. These terminals are suitable for solid conductors as well as tinned or with multicore cable end, stranded wires up to 1.5mm2. To make a termination, push the wire into the terminal or insert a small screwdriver from the front of the controller into the spring-release hole and insert the wire. Check for proper connection by short pull on the wire. Wiring should be done only according to the actual job wiring diagrams or wiring diagrams shown in the mounting instruction sheet EN1B-0202GE51. The wiring to the CPA/SPA potentiometers is described in Table 1. All wiring must conform to local applicable codes, ordinances, and regulations. The maximum allowed wiring length per wire size are shown in Table 2.

CONFIGURATION SETTINGS

All configuration parameters have to be set to select the correct control functions as required for the job application.
Direct - Reverse Action Dir/RevY1 (C.01)
The output action of the analog output must sometimes be reversed for a correct opening and closing direction of the valve or damper. This depends on whether the output controls a 2-way or 3-way valve or on the direction the damper shaft moves to open the damper (cw or ccw). It is only needed, if the actuator does not provide a direction selector switch, plug or similar. Note: The analog output signal Y1 can be displayed in the standard display mode. The selected action of signal Y1 does not influence the display indication.

1000 at 0C 500 at 23.3C 20k at 25C
NTC sensor is detected automatically, if during power up the sensor temperature is within -30.+85C and Senstyp = 0. NTC sensor is selected manually, if Senstyp is set to 1. Table 5. Sensor Types
Control Point / Setpoint Adjustment CPATYP (C.05)
The control point or setpoint can be adjusted via the internal or an external potentiometer connected to the CPA/SPA input. The potentiometer type is selected by CPATYP (see Table 3).
Automatic identification of sensor type is selected, if Senstyp = 0 (default). After power up reset the controller detects automatically the type of sensor, which is connected to the temperature input T3. For a correct auto detection, it is necessary that the measured temperature is in the specified range (see Table 5).

Output Control Function Y1CTRF (C.15)
The R7426D controller performs direct control behaviour, if Y1CTRF is set to 0. A rise in the measured variable will increase the output value from 0.100% (direct acting). The control action must be reversed for reverse control behavior by setting Y1CTRF to 1. A rise in the measured variable will decrease the output value (100.0%). Note: The analog output signal Y1 with the selected control behavior is displayed in % in the standard display mode.
Output Control Range Selection YRange (C.06)
YRange is required to select the output control range (0.100%) to either 2.10Vdc (YRange = 0) or 0.10Vdc (YRange = 1).
Supply of Input Signal X2ext (C.12)
X2ext has to be set to 1, if the sensor input X1 is also used for high or low limit control. This interconnects the X1 and X2 input internally and the sensor has to be connected only to the X1 input. When using a limit sensor X2, the parameter X2ext has to be set to 0 (default). If sensor X2 is not used, the input has to be deactivated by setting X2ext to 2.
Serial Communication Address Adr(C.22)
The parameter Adr sets the serial communication address, used for controller start-up, service or maintenance purposes via the bus.

Limit Type LimTyp (C.13)

LimTyp allows the selection of high or low limit control. High limit control is performed if LimTyp = 1 and low limit control is performed if LimTyp = 0.
Default Programming DefProg (C.23)
Setting DefProg to 1 resets all control and configuration parameters to defaults (see Table 3 and Table 4). Default programming is indicated by a display of def. After default programming, the parameter DefProg is reset to 0.
Sensor Type Senstyp (C.14)
Three different sensor types can be used on input T3 with the controller (see Table 5).
Span Adjustment UStartPoint / UendPoint (C.24 / C.25)
The universal inputs X1 and X2 accept any analog inputs within the range of 0.10Vdc and provides an input span adjustment to match the range of the connected transmitters. The start / end point of the input span can be adjusted by the parameters UStartPoint / UendPoint and is converted to a 0.100% input range. The parameters UStartPoint and UEndPoint are common for both inputs X1 and X2.
Off Delay for On/Off Output (C.26)
The On/Off output is controlled by the Plant / System On/Off input and provides an Off switching output with adjustable delay time e.g. to operate the fan still for a certain time after humidification.
On/Off Input Controller Function On/Off Output: Delay
Reset Span Adjustment Rcas (P.07)
The reset span adjustment Rcas determines the reset effect in %, the submaster setpoint Wcas is altered, if the main input (X1) deviates by 50% of the throttling range Xp1.

Throttling Range Xp1 / Xp2 (P.08 / P09)
Throttling range Xp adjustment determines the controller variable change, required at the main sensor (X1) and limit or cascade sensor (X2) to operate the output device from full open (100%) to full closed (0%) or vice versa. Xp1 is the throttling range for the main control loop, Xp2 is the throttling range for limitation or cascade control (submaster control loop).
Application Sens. Xp1 Xp2 tr1 tr2 vd/td

PARAMETER SETTINGS AND ADJUSTMENT

Main Setpoint W1 (P.01)

The main setpoint is either set by the parameter W1 (CPATYP = 0 or 1) or by the external setpoint potentiometer (CPATYP = 2).
R7426D Controller Main Control High or Low Limit Control Cascade Control Master Submaster X1 X2 x x x x x X1 X2 x x x x x x
High/Low Limit Setpoint Wlim (P.02)
For high or low limit control, the control parameter Wlim is used as setpoint. During limit control, the throttling range Xp2 and reset time tr2 are active. Limit control will be active only, if the X2 signal (X2ext = 0) is available or alternatively the sensor X1 (X2ext = 1) is used also for limit control. For cascade control the limit setpoint Wlim determines the control point at which the submaster setpoint (Wcas) maintains the limit value and is not shifted anymore by the master control loop. High or low limit control is in accordance with the parameter LimTyp (C.13).
Table 6. Throttling Range, Reset and Derivative Time Reference
Setting Guidelines for Proportional Band of P, P+I and P+I+D Control
To estimate the proportional band (throttling range Xp) for stable control under all different load conditions the control or correcting range Xh of the controlled variable by the final controlling element has to be known. This is the maximum difference in the controlled variable between the fully closed and fully open position of the final controlling element (e.g. valve). The proportional band Xp for discharge air control can be calculated by using the following rule-of thumb formula:

Xp = Xh 5

Submaster Setpoint Wcas (P.06)
The R7426D controller provides cascade control which uses two control loops, master and submaster to maintain the master setpoint CTRP1. Cascade control will be active, if sensor X2 is connected and the control parameter Wcas is set to any value other than Off. This adjustment sets the control point of the submaster control loop, cascade input (X2), at zero deviation of the master control loop. If the controlled input X1 deviates from the master setpoint CTRP1, the submaster setpoint Wcas is automatically altered (CTRP2). Cascade control is disabled, if the submaster setpoint Wcas is set to Off. Low limit of CTRP2 is performed if control parameter LimTyp = 0 and high limit of CTRP2 is performed if control parameter LimTyp = 1.

For room control the following rule-of-thumb formula can be used:

Xp = Xh 10

In P+I or P+I+D control the same proportional band can be used as for P control. The following rule-of-thumb formula are used for P+I control: Discharge air control Room control

Xp = Xp = Xh 4.5 Xh 8.10

The following rule-of-thumb formula are used for P+I+D control: Discharge air control Room control
Xp = Xp = Xh 5.6 Xh 10.12
Setting Guidelines for Reset Time of P, P+I and P+I+D Control
The reset time tr should be adjusted to 2.3 times of the response time Tu , which is the time interval between the beginning of a sustained disturbance (e.g. rapid step change of valve position) and the instant when the resulting change in the output signal reaches a specified fraction of its final steady-state value, either before overshoot or in the absence of overshoot. The response time Tu in discharge air control is normally in the range of 0.1 to 0.6min, which allows adjustments of the reset time tr in a range of 0.2 to 2min. In room control the response time Tu is in the range of 0.5 to 5min, which results in a setting of 1 to 15min.
Resetting Time tr1 / tr2 (P.12 / P13)
In the case of combined action including proportional and integral components (P+I control) the reset time (tr) is defined as the required time after which the integral part is equal to the change due to the proportional action for a predetermined step change in the input variable. See Fig. 3. The control parameter tr1 sets the reset time of the P+I main control loop. For limit or submaster cascade control (input variable X2) the control parameter tr2 sets the reset time of these control loops (see Table 6). If only proportional control is required parameter tr has to be set to Off.
Xw 0 t Y P + I controller P 100 P = X Xw %
Derivative Decay Time td and Amplification vd (P.27 / P.28)
The Proportional + Integral + Derivative (P+I+D) control adds the derivative function to P+I control to enhance the control behavior. The derivative function opposes any change and is proportional to the rate of change (derivative). If the controlled input X1 deviates from the master setpoint (CTRP1), the derivative function outputs a corrective action to bring the control variable X1 back more quickly than by integral action alone. The derivative amplification vd determines the effect of derivative action after a rate of change of the controlled input X1. The decay time td determines the decay of the control output Y1 after derivative action (see Fig. 3).

P %/s tr

tr Y P vd % P 100 P = X Xw % p td tr P + I + D controller
In main control and cascade control applications the control parameters td and vd determines the derivative function. In main control with limitation control these parameters determines the two derivative functions of main control and limitation control.

Setting Guidelines for Derivative Amplification and Decay Time of P+I+D Control
The proper setting depends on the time constants, e.g. the response time Tu , of the system being controlled. The parameter vd and td can be set in the following relation:

td = 0.42 Tu vd

Fig. 3. Step change response of P+I and P+I+D control Note: P+I+D control is available for main control and main control with limitation control. In cascade control the submaster is P+I+D controlled while the master is P+I controlled.
In other words, with derivative amplification vd set to 1, the decay time td should be set to approx. 0.42Tu or approx. (0.15.0.25)tr. The response time Tu in discharge air control is normally in the range of 0.1 to 0.6min, which allows adjustments of the decay time td in a range of 2.5 to 15sec.
Start Point Ystart (P.15)
The start point setting determines the relationship between the midrange shift of the output Y1 and the corresponded calculated control point. It is calibrated in %, e.g. r.h., and is the change (plus or minus) from the control point. In humidification and dehumidification control the start point has to be shifted by minus 50% of the proportional band Xp1. Example: Set YCTRF to 1, reverse control behavior Set Xp1 at 6% Set start Ystart at minus 3% With these settings, the humidifier valve will be fully closed, if the actual humidity value is equal to the calculated control point CTRP1 (zero deviation) and fully open at 6% r.h. below CTRP1. At 6% r.h. above CTRP1, the controller provides an output signal of plus 1200mV (100%) to fully open the cooling valve by the plant temperature controller for dehumidification. In P+I+D and P+I control the start point has to be set to the same value as for P control.

Compensation Changeover Point Wcomp (P.03)
The control parameter Wcomp defines the start point of summer or winter compensation. Above the compensation changeover point (Wcomp) summer compensation and below Wcomp winter compensation is performed.
Table 7. Calculation of Summer/Winter Compensation
Calibration of Sensors X1CAL, X2CAL or T3CAL (P.17.P.19)
The controllers include a calibration setting and are factory calibrated. In case of an offset as a result of long wiring lengths the sensor inputs (X1, X2 and T3) can be adjusted separately by the control parameters X1CAL, X2CAL and T3CAL.

Summer / Winter Compensation Authority Su / Wi (P.04 / P.05)
These authority settings determine the reset effect (TComp) of the compensation sensor (T3) on the main setpoint W1 in percentages. To calculate winter and summer authority for e.g. humidity control, the throttling range has to be considered in proportional only control according to Table 7.
