9.3.5.1 Service mode parameters
The following parameters are parameterised on the parameter page "General ->
General - Valve outputs -> Enabled functions".
Service mode
Service mode allows the bus-controlled locking of the valve output in case of main-
tenance or installation. If service mode is active, actuators can be moved to a
defined position (completely open or closed) and locked against activation by com-
mand value telegrams.
Active: Service mode is enabled. The communication object "Service mode - Deac-
tivate / activate input" becomes visible.
Inactive: Service mode is not available.
The following parameters are parameterised on the parameter page "General ->
General - Valve outputs -> Service mode".
Behaviour at the end
This parameter specifies the state which the valve output goes into on when service
mode is deactivated.
Restore last status after bus voltage re-
turn
This parameter defines whether the previous service mode state is automatically re-
stored after bus voltage return.
9.3.5.2 Objects for service mode
Function: Activate / deactivate service mode
Object no.
16
2-bit input object for activating and deactivating service mode. With the value "1", bit
1 of the telegram activates service mode. The assigned valve outputs are then
locked in the status preset by bit 0 ("0" = Closed / "1" = Opened). The configured
valve direction of action is taken into account. The value "0" in bit 1 deactivates ser-
vice mode again.
0x = Service mode deactivated
10 = Service mode activated, valves closed
11 = Service mode activated, valves opened
