15.1.15 Inhibit Delay Settings
Access Level: Engineer
Parameter Name Default Setting Value Range Comment
Power-On Delay Enable Enabled Enabled / Disabled If enabled, the channel will be inhibited for a specific time
interval (the Inhibit Delay Time) after power-up in order to
prevent false alarms (e.g. during sensor warm-up).
Fault Recovery Delay Enable Enabled Enabled / Disabled If enabled, the channel will be inhibited for a specific
time interval (the Inhibit Delay Time) after a channel fault
condition has been cleared in order to prevent false alarms
(e.g. due to sensor recovery).
Inhibit Delay Time 30 s 0 to 3000 s This is the delay time before a channel returns to normal
operation if the Power-On Delay or the Fault Recovery
Delay are enabled.
15.1.16 Signal Range Fault Settings
Note: When setting up the Gas Over / Under Range and Signal Over / Under Range limits, take account
of any diagnostic signals that may be generated by the eld device under and over the measuring
range. Failure to do so may result in confusing or misleading messages. Remember that up to 5 Custom
Transmitter Faults and Inhibit Signalling are available, so that diagnostic information from the transmitter can
be clearly understood.
Note: When commissioning or testing sensors with a Transmitter, check that all fault messages from the 4-20
mA transmitter match the Touchpoint Pro settings.
Some typical diagnostic signal levels and equivalent %FSD values that may be used by intelligent
transmitters are given below:
Diagnostic level Equivalent %FSD
22 mA 112.5 %
21 mA 106.25 %
3 mA -6.25 %
2.5 mA -9.4 %
2 mA -12.5 %
1.5 mA -15.6 %
1 mA -18.75 %
