Software ESD Action
This is where the ESD action of the actuator is defined. There are four available options:
De-energise all Solenoid Valves: On receiving an ESD signal the actuator will de-energise all solenoid
valves fitted.
Close Actuator: When receiving an ESD signal the actuator will run to its closed limit position.
Open Actuator: When receiving an ESD signal the actuator will run to its open limit position.
Stay Put: When receiving an ESD signal the actuator will not move from its position and stop if it is
currently travelling in either direction.
ESD Local Stop Override
This feature dictates whether an active ESD signal will override a present local stop. There are two
available options:
No: Select this option if a software ESD command should NOT override the local stop.
Yes:
Select this option if a software ESD command should override a present local stop.
ESD Contact Type
This setting determines if a signal should be applied or removed to initiate a software ESD action. There
are two available options:
Normally Open: The ESD signal has to be applied to perform a software ESD function.
Normally Closed: The ESD signal has to be removed to perform the set software ESD function.
ESD Manual Reset
This feature dictates the reset option for the ESD state. There are four available options:
No Reset: Set this option if the actuator does not need to be reset after an ESD event or loss of mains
power.
After ESD: Set this option if the actuator must be manually reset after an ESD event.
After Mains Loss: Set this option if the actuator must be manually reset after loss of mains power.
ESD/Mains Loss:
Set this option if the actuator must be manually reset after an ESD event of loss of
mains power.
