When the system is set ON (on= Stop) change the status, as follow:
•
All relays are disabled
•
All outputs are disabled (not freq. signal, outmA frozen at 4 hold value)
•
All alarms are disabled
•
All manual pump activations are disabled
•
Keyboard button are enabled
•
Reset parameters function is disabled
•
Interrogating the device via Modbus will not show the alarms
•
Once the “remote stand by” is deactivated, the device restarts from the status before remote Stop
event.
•
Input level and Flow input are detected but if we have an alarm it doesn’t generates any alarm on
Modbus or on Alarm relay.
Some basic recommendations for connecting the RS485 line:
All devices on the line must be connected “one after the other” and not in a “star”
(see image on the right).
