CT
Option: Heater burnout alarm
CT input
Lower part of main body
This alarm is not available for detecting current under phase control
.
Use the current transformer (CT) provided, and pass
a lead wire of the heater circuit into a hole of the CT.
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
approx. 3 seconds (Table 5-1).
(If any other value is set in the scaling high limit value, it 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 setting value will be
indicated on the SV display.
