2.8.2 'Power ok' signal
The "Power ok" relay is triggered by the hardware monitoring of the
internal supply voltages and the temperature sensor.
The "Power ok" relay is switched off when the power supplies do
not match the allowed range or the internal temperature is too high.
n Use the contacts of the "Power ok" relay to switch off the main
power supply of the control unit to avoid any unexpected dam-
ages to the control unit.
The contacts for 'CNC Ready' and 'Power OK' are available on
connector X19.
– When an external 5V power supply (RMS) is
necessary to supply incremental measuring
systems, use the corresponding entry in the
control unit's drive configuration file
(DriveCfg.ini) to activate the monitoring of
the correct range of these 5 V.
When the monitoring is activated, an error on
this power supply will cause the "Power ok"
relay to drop.

DANGER!
Use all CNC Ready contacts!
When a Power Automation control unit is used in
association with PAMIO components of type
4ENC4A it is necessary to use both the CNC
Ready contacts of the control unit and those of
these PAMIO components in the Emergency Stop
Chain.
