Figure 28 shows an example of the flashing patterns for the EMD expansion safety relay.
The status indicators flash for 0.5 seconds to indicate the switch settings. The number
of flashes is equal to the switch setting. The flashing pattern repeats after a 2 second
pause.

5. Cycle the power to store the settings.
After power-up, the current switch settings are compared to the values in the EEPROM
(makes sure that the switches were not changed while power was off), and the input
and output circuits are checked. Upon successful completion of the internal checks,
the safety relays are ready for operation.
