6.1.1 Dry Contact Outputs
Alarm & Communication Interface Board option provides 2 dry contact outputs to the user. Dry
contact outputs can be programmed by the user via the LCD panel or Modbus communication,
depending on the requirement. Although the features of the model is deterministic, the following
status can be programmed for the dry contact outputs:
DC Low
DC High
DC Too Low
Over Temperature
IGBT / IPM Fault
Memory Error
Earth Leakage (OPS-02)
Fan Failure (Option depending on user requirement)
Breaker Open (Option depending on user requirement)
Fuse Failure (Option depending on user requirement)
Door Open (Option depending on user requirement)
Hardware Block (Option depending on user requirement)
Dry contacts remain energized, when the alarm condition is not occoured. When the programmed
condition occours (for example, if DC High alarm is detected), dry contact is releases and switches
to unenergized state. Dry contact outputs are provided to the user directly from plugin sockets
placed on the Alarm & Communication Interface Board.
NOTE
Maximum 24Vac or 24Vdc voltage should be applied to dry contacts. Dry contacts are for signaling
purposes and can carry maximum 0.5A current.
