ACTUATOR INSTALLATION
The switches on the circuit board should
be set before the actuator is installed.
There are no other switches or
potentiometers that should be set or
adjusted.
To make an end position adjustment, you
only have to switch the switch »OP/ADJ«
into its ADJ position, when the supply
voltage has been turned on, and then
back to its OP position.
When an end position adjustment is made,
Forta closes the valve and opens it fully.
The adjustment is finished by the actuator
closing the valve again; the electronic
circuitry then adjusts the stroke and the
running time to the valve. The set values
are stored in the EEPROM of the actuator
so that they will remain after a loss of
voltage.
When the end position adjustment is
complete, the actuator starts to control the
valve according to the control signal.
MAINTENANCE
The actuator is maintenance-free.

Hot media hazard. Before removing
actuator from valve or opening the valve,
ensure that the valve control medium is
isolated and relive the pressure. Work
should only be carried out by a competent
engineer.
