Pleiger Control Loop
Manual version 2018-03
10.4.4 General symbols
The busmasters are connected via a serial comunication
(CANBUS). This comunication is faulty.
The PLD is enabled to control all valves of this busmaster .
Attention
: This includes that the SCADA system can’t control
any valve.
With this button you can enable the control from PLD for all
valves of this busmaster .
Table 10-5: General symbols
CAUTION
Malfunction / Dangerous situation
If the function “All Valves Local” is activated (only possible with the right permission),
full control over this busmaster pair is switched over to the PLD.
Actuators can’t be controlled by the SCADA system any more. All automatic functions
(like heeling
, bilge operation, …) won’t be longer available!
Digital outputs (on PCL-VCI and PCL-IO) can be still controlled by the SCADA system.
If the input is true, the area is colored green.
In case of a quick close input the meaning of the input is reverse.
The quick close circuit is active if the circuit is open.
Then the input is false and the area is colored red. If a node is parametrized with
an opened quick close circuit you see the message in the picture of the node.
The quick close input is only shown if a node is parametrized with this input.
The system has no power supply if the power1 input and the power2 input are
false. In this case the red area is highlighted.
NOTICE
Monitoring state (only)
In this case the busmaster is supplied by an UPS. Only drive states
monitoring is possible, no actuator can be operated!
Spring closed / opened actuators close / open automatically!
