Option: Heater burnout alarm

(1) This alarm is not available for detecting heater current

under phase control.

(2) Use the current transformer (CT) provided and pass one

lead wire of the heater circuit into the hole of the CT.

(3) When wiring, keep the CT wire away from AC sources

or load wires to avoid the external interference.

5. Setup

Wire the power terminals only. After the power is turned on, the sensor input characters and temperature

unit are indicated on the PV display and the input range high limit value is indicated on the SV display for
approximately 3 seconds (Table 5-1).

If any other value is set during the scaling high limit setting, the set value is indicated on the SV display.

During this time, all outputs and the LED indicators are in OFF status. Control will then start and the input
value will be indicated on the PV display and main setting value (SV) will be indicated on the SV display.
(While control output OFF function is working,

is indicated on the PV display.)
