Setting instructions for actuator
including an interrupter timer.
The interrupter timer enables pulsed
“stop/start” operation by the actuator
as a response to local and remote
control commands.
This effectively increases the valve
stroke time and can be adjusted to
prevent hydraulic shock (water
hammer) and flow surges in pipelines.
The interrupter timer is an optional
extra – check wiring diagram for
inclusion.
When fitted, the timer will be
made available for operation.
The Interrupter cannot be
enabled or disabled using the
Setting Tool.
