Relays
The converter is fitted with 2 output relays serving as
interface with the centralized control, e.g.: control box,
pump control.
SBM relay:
This relay can be configured in „Service" menu <
5.7.6.0 > in 3 operating states.
State: 1 (set by default)
„Available transfer" relay (normal operation of
this pump type).
The relay is activated when the pump is running or
in standby.
The relay is deactivated if an initial defect occurs
or if the main power supply is disconnected
(pump stops). Pump availability is signalled to the
control box.
State: 2
„Run transfer" relay.
The relay is activated when the pump is running.
State: 3
„Power on transfer" relay.
The relay is activated when the pump is connect-
ed to the network.
SSM relay:
„Failures transfer" relay.
If consecutive defects of the same type are detected
(from 1 to 6 according to significance), the pump
stops, and the relay is activated (until manual interven-
tion).
Example: 6 defects with a variable time limit within 24
hours.
State of SBM relay is „Available transfer".
