Operating the F01-2000
Section 5: Operating the F01-2000
5.7.3 ESD Operation
An ESD (Emergency Shut Down) signal can be sent to the actuator to override any existing
command and to drive the valve to a predetermined position.
The control is not self-maintained, that is, the ESD action continues until the relevant signal
is present. The “VIEW and SET-UP” features can congure different ESD options.
The ESD command is opto-coupled.
The circuits associated to the input 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 DC or V AC
Current drawn from ESD controls < 15 mA
!
WARNING
If customers wish the motor thermostat to be bypassed during ESD operation any
certication for actuator enclosure in hazardous area would be invalidated.
