Instructions for the Fail Safe State
When the power supply is switched on, the vibration monitoring unit will perform a self-test.
During operation, self-tests are performed automatically in cycles. If a self-test fails, the vibration
monitoring unit switches to the Fail Safe State.
In the Fail Safe State all status LEDs are lit, all relays are open and the analogue current output
supplies 0 mA.
