CN7200/CN7500 CN7600/CN7800

Thank you very much for choosing Omega Engineering Series CN7200/CN7500/CN7600/CN7800 Temperature/Process Controller. Please read this instruction sheet before using your controller to ensure proper operation and please keep this instruction sheet handy for quick reference.

DANGER! Caution! Electric Shock!

1. Do not touch the AC terminals while the power is supplied to the controller to prevent an electric shock.

2. Make sure the power is disconnected while checking the unit inside.

3. The symbol indicates that this Controller is protected throughout by DOUBLE INSULATION or REINFORCED

INSULATION (equivalent to Class II of IEC 536).

WARNING!

Mount the controller in a location that will not be subject to excessive temperature, shock, or vibration. All models are designed for mounting in an enclosed panel.

1. Always use recommended solder-less terminals: Fork terminal with isolation (M3 screw, width is 7.0mm (6.0mm for 32B

Series), hole diameter 3.2mm). Screw size: M3 x 6.5 (With 6.8 x 6.8 square washer). Screw size for 32B Series: M3 x 4.5 (With 6.0 x 6.0 square washer). Recommended tightening torque: 0.4 N.m (4kgf.cm). Applicable wire: Solid/twisted wire of

, 12AWG to 24AWG. Please be sure to tighten them properly.

2 mm

2. Do not allow dust or foreign objects to fall inside the controller to prevent it from malfunctioning.

3. Never modify or disassemble the controller.

4. Do not connect anything to the “No used” terminals.

5. Make sure all wires are connected to the correct polarity of terminals.

6. Do not install and/or use the controller in places subject to: Dust or corrosive gases and liquid, high humidity and high

radiation, vibration and shock, high voltage and high frequency

7. Power must be off when wiring and changing a temperature sensor.

8. Be sure to use compensating wires that match the thermocouple types when extending or connecting the thermocouple

wires.

9. Please use wires with resistance when extending or connecting a platinum resistance sensor (RTD).

10. Please keep the wire as short as possible when wiring a

power wires as far as possible from load wires to prevent interference and induced noise.

11. This controller is an open-type unit and must be placed in an enclosure away from high temperature, humidity, dripping

water, corrosive materials, airborne dust and electric shock or vibration.

12. Please make sure power cables and signals from instruments are all installed properly before energizing the controller,

otherwise serious damage may occur.

13. Please do not touch the terminals in the controller or try to repair the controller when power is applied to prevent an electric

shock.

14. Wait at least one minute after power is disconnected to allow capacitors to discharge, and please do not touch any internal

circuit within this period.

15. Do not use acid or alkaline liquids for cleaning. Please use a soft, dry cloth to clean the controller.

16. This instrument is not furnished with a power switch or fuse. Therefore, if a fuse or power switch is required, install the

protection close to the instrument. Recommended fuse rating: Rated voltage 250 V, Rated current 1 A. Fuse type: Time-lag fuse

17. Note: This controller does not provide overcurrent protection. Use of this product requires that suitable overcurrent

protection device(s) must be added to ensure compliance with all relevant electrical standards and codes. (Rated 250 V, 15 Amps max). A suitable disconnecting device should be provided near the controller in the end-use installation.

Description of Function and Parameters Setting:

To set-up or edit the ramp/soak function, follow in the menu list.

The Ramp and Soak function is supported by 8 different patterns (Pattern No. 0 ~ 7). Each pattern contains 8 steps (step No. 0 ~ 7) for set point and execution time, one Link Pattern parameter, one Cycle parameter and one Actual Step parameter.

The set point (SV) should reach temperature X after the execution time T. The default of step No. 0 is soak control. The unit will control the temperature (PV) to reach the set point X and then keep the temperature at set point X. The execution time T is determined by step No, 0.

Temperature control can be achieved either by heating or cooling. In the CN7200/CN7500/CN7600/CN7800 series, heating and cooling can be operated simultaneously (Dual Loop output control) to perform temperature control. When Dual Loop output control is used, two control outputs must be connected to the heating and cooling devices. Please refer to the following for the operation: Settings for heat, cool, or heat

Depending on the controller model, there can be up to three alarm outputs. Each alarm output can be configured for an alarm type listed below. Alarm types are set in the initial setting mode. The alarm output is activated whenever the process temperature value (PV) is getting higher or lower than the set point of alarm limit.

Deviation upper- and lower-limit:

This alarm output operates when PV value is higher than the setting value SV+(AL-H) or lower than the setting value SV-(AL-L). Deviation upper-limit:

This alarm output operates when PV value is higher than the setting value SV+(AL-H).

Deviation lower-limit: This alarm output operates when PV value is lower than the setting value SV-(AL-L).

Reverse deviation upper- and lower-limit:

This alarm output operates when PV value is in the range of the setting value SV+(AL-H) and the setting value SV-(AL-L). Absolute value upper- and lower-limit:

This alarm output operates when PV value is higher than the setting value AL-H or lower than the setting value AL-L. Absolute value upper-limit:

This alarm output operates when PV value is higher than the setting value AL-H.

Absolute value lower-limit:

This alarm output operates when PV value is lower than the setting value AL-L.

Deviation upper- and lower-limit with standby sequence:

This alarm output operates when PV value reaches set point is higher than the setting value SV+(AL-H) or lower than the setting value SV-(AL-L). Deviation upper-limit with standby sequence:

This alarm output operates when PV value reaches set point (SV value) and the reached value is higher than the setting value SV+(AL-H). Deviation lower-limit with standby sequence:

This alarm output operates when PV value reaches the set point (SV value) and the reached value is lower than the setting value SV-(AL-L). Hysteresis upper-limit alarm output:

This alarm output operates if PV value is higher than the setting value SV+(ALalarm output is OFF when PV value is lower than the setting value SV+(AL-L). Hysteresis lower-limit alarm output:

This alarm output operates if PV value is lower than the setting value SV-(AL-H). This alarm output is OFF when PV value is higher than the setting value SV-(AL-L). CT alarm output: This alarm operates when the current measured by transformer (CT) is lower than

AL-L or higher than AL-H (This alarm output is available only for the controller with current transformer).

14 When program control is end status, alarm output is ON. 15 When RAMP UP status happens to PID program control, alarm output is ON. 16 When RAMP DOWN status happens to PID program control, alarm output is ON. 17 When SOAK status happens to PID program control, alarm output is ON. 18 When RUN status happens to PID program control, alarm output is ON.
