Operating the F01-2000
Section 5: Operating the F01-2000

Interlock Inputs
Two additional inputs are available to inhibit actuator movement in open or close direction.
The controls are momentary, and the inhibit action continues until the relevant signal is
present. The interlock controls work when the local selector is in either LOCAL or REMOTE
positions. The ESD control overrides the interlock controls. The “VIEW and SET-UP”
features can configure the polarity of INTERLOCK signal as described in Section 9.1.10.
The interlock inputs are opto-coupled and can be supplied by the internally generated
24 V DC or by an external 20-125 V DC or 20-120 V AC (50/60 Hz).
The signal levels are the following:
•
Minimum ON signal > 20 V DC or 20 V AC (50/60 Hz).
•
Maximum ON signal < 125 V DC or 120 V AC (50/60 Hz).
•
Maximum OFF signal < 3 V.
•
Total current drawn from remote controls < 20 mA.

Operating the F01-2000 for the First Time
Before attempting to operate the F01-2000 for the first time, check that the actuator is
correctly mounted on the valve. Place the 3-position selector in OFF and switch the power
on. The alphanumeric display shows the following message for about 3 seconds:

or:
