CND3 Series Temperature Controller

 Warning

DANGER! Caution! Electric Shock! When the power is on, DO NOT touch the AC terminals in case an electric shock may occur. Make sure the power is disconnected when you check the input power supply.

1. Prevent dust or metallic debris from falling into the controller and cause malfunctions. DO NOT modify or uninstall the controller.

2. CND3 controller is an open-type device. Make sure it is installed in an enclosure free of dust and humidity in case of an electric shock.

3. Wait for one minute after the power is switched off to allow the capacitor to discharge. DO NOT touch the internal wiring within this period of time.

 Alarm Outputs

CND3 offers 3 alarm outputs, and each alarm output has 20 alarm modes to choose from in the initial setting mode. When the target temperature exceeds or falls below the set point, the alarm output will be enabled.

SV Alarm mode Alarm output operation

0 No alarm

Alarm output will be enabled when the temperature reaches upper or

lower limit: The alarm will be enable when the PV exceeds SV + AL-H or falls below SV – AL-L.

Alarm output will be enabled when the temperature reaches the upper

limit: The alarm will be enabled when the PV exceeds SV + AL-H.

Alarm output will be enabled when the temperature reaches the lower

limit: The alarm will be enabled when the PV falls below SV – AL-L.

Alarm output will be enabled when the temperature reaches the

absolute value of the upper or lower limit: The alarm will be enabled when the PV exceeds AL-H or falls below AL-L.

Alarm output will be enabled when the temperature reaches the

absolute value of the upper limit: The alarm will be enabled when the PV exceeds AL-H.

Alarm output will be enabled when the temperature reaches the

absolute value of the lower limit: The alarm will be enabled when the PV falls below AL-L.

Upper limit hysteresis alarm: The alarm will be enabled when the PV

exceeds SV + AL-H. The alarm will be disabled when the PV falls below SV + AL-L.

Lower limit hysteresis alarm: The alarm will be enabled when the PV

falls below SV – AL-H. The alarm will be disabled when the PV exceeds SV – AL-L.

Offline alarm: The alarm will be enabled when the input sensor is not

correct or offline.
