Hach sc200 User Manual

Do not use On-Delay for any safety critical function. Use
only for Process control. Failure to follow the above can
result in personal injury or loss of life.
F9- Remote Relay Editor
(Optional: Requires Remote Relay Modules)
Enter 30 if only one remote relay is on the network, 31, for two remote
relays, 32 for three remote relays and 33 for four remote relays. To
activate or Deactivate remote relays, enter F2 to Enable or Disable.
Optional: Remote Relay units
A total of four remote relay units may be added to the modbus network
(see Appendix C for additional details). Modbus ID numbers of the
remote relay modules must be programmed for ID#30, 31, 32 or 33.
Input Remote Relay on all remote units is the local silence alarm.
Closing this input will silence the local alarm as well as the ModCon75
Alarm. Output O0 is for the local alarm output.
Note: If Zone Alarms are programmed as Latch, one can silence the
alarm at the remote relay, but the Zone alarm will not be
cleared until the unlatch input is initiated at the ModCon75
Controller.
Following would be used for remote alarms:
