Three PS598-1 units for two devices - 2-out-of-3 redundancy
Connect each SCALANCE XR-500M to its own PS598-1. In addition to this, connect
both SCALANCE XR-500M devices to the third PS598-1. Both SCALANCE XR-500M
devices can now continue to operate after the failure of one PS598-1. The
SCALANCE XR-500M detects the failure of a power source and signals the failure.
The PS598-1 units share the applied load automatically and uniformly.
Note
Two connectors for the 24 VDC output voltage
The PS598-1 has two connectors with the output voltage 24 VDC. Note that you can
only use the connector on the front or the connector on the rear of the PS598-1. You
cannot operate the device with the connectors on the front and rear at the same time.
LED display
A PS598-1 has two LEDs each, one green and one red. If the green LEDs is lit
(24V OK), the output voltage is correctly applied. If the red LED is lit (SHUT DOWN)
an error has occurred.
Possible errors/faults:
●
The output voltage is not correct.
●
Temperature of the PS598-1 is too high.
