■ Failure Detection Function
Conditions for SSR Failure Detection
Note: 1. The contents of each of the above failure modes is as follows:
SSR short-circuit: SSR output circuit remains in the ON state.
SSR half-wave short-circuit: SSR output circuit remains in the ON state in one direction.
SSR open-circuit: SSR output circuit remains in the OFF state.
SSR half-wave open-circuit: SSR output circuit remains in the OFF state in one direction.
In addition to the failure modes listed above, detection of circuit disconnections for the load circuit is also possible. (As a rough guide,
circuit disconnection will be detected if the load impedance is greater than or equal to 1 M
Ω.)
2. The same power supply is used for both the detection and for the output circuit and so detection is not performed during power
interruptions.
3. If power supply (terminal 3) is in the open state, the SSR will still turn ON and OFF in the same way but the failure detection function and
alarm display will not operate properly.
Connection Diagrams (Main Circuit)
The following diagrams show the applicable load connection configurations for SSR failure detection.
Note: 1. With 3-phase connection, so that the power supply voltage is applied between the G3PC’s terminals 1/L1 and 3, connect the desired
phase to terminal 3.
2. When grounding to a neutral point with a three-phase start connection, an overvoltage will be applied to the G3PC if the neutral point
becomes disconnected, possibly causing product failure. Make sure the connection to the neutral point is secure.
3. Detection is not possible for the heater indicated with an asterisks with a three-phase delta connection.
Timing Chart
Note: After failure detection, if the detection conditions differ to the conditions given under Conditions for SSR Failure Detection, alarm output is
reset.
