Test Input Function - Panasonic SQ4-C11 Instruction Manual

3-3 Test Input Function

It is the function to check normal operation by turning ON / OFF control outputs 1 / 2 (OSSD 1 / 2)
of the controller without generating a liquid leak condition at the sensor.
When the test input terminal between T1 and T2 is open, valid operation can be selected, and
when it is shorted, invalid operation (normal operation) can be selected.
Use a conductor (contact, copper wire, etc.) for short-circuit. A semiconductor (transistor) etc.
may not ensure normal operation.
