ESD Temporary Loss of Signal
This shows the options for the actuator under a temporary loss of an ESD signal. The available options
are:
Stop Actuator, Move if Signal is Present: Meaning the actuator will stop and wait for the ESD signal to
be restored before continuing the ESD actions
Stop Actuator, Wait for New Signal: Meaning the actuator will stop and wait for a new ESD signal to be
sent before continuing the ESD action
Continue ESD action: Meaning if the signal is temporarily lost the actuator will continue to perform its
ESD action.
8.5.2 Partial Stroke
Partial Stroke Position (%)
This is the set position that the actuator will move to when a partial stroke test is performed. The
current settings for the analogue input deadband and hysteresis values will be used during the partial
stroke test. The available range is 1% to 99% at 1% increments.
General Tolerance (sec)
This is the acceptable tolerance for the partial stroke test time in addition to 8.5.3 reference strokes.
E.g. with a 1.5 second tolerance and 15 second reference stroke time to total allowable time before a
failure is recognised is 16.5 seconds.
8.5.3 Reference Partial Stroke Test Recorded Values
The partial stroke reference test values are recorded by performing the partial stroke setup at the
actuator (refer to pub021-033).
Time to Partial Stroke Position (1st Stroke)
For indication only, displays the time from the set end of travel limit, for the actuator to reach the set
partial stroke position (refer to 8.5.2).
Time to Partial Stroke Position (2nd Stroke)
For indication only, displays the time from the set end of travel limit, for the actuator to reach the set
partial stroke position (refer to 8.5.2).
Time from the Partial Stroke Position to Limit (1st Stroke)
For indication only, displays the time from the set partial stroke position (refer to 8.5.2), for the actuator
to reach the set end of travel limit.
Time from the Partial Stroke Position to Limit (2nd Stroke)
For indication only, displays the time from the set partial stroke position (refer to 8.5.2), for the actuator
to reach the set end of travel limit.
