3.5.7
Signal Output Check
Signal Output Check
provides a simulated 4-20mA output and RS-485 Modbus™ output. This simulation
allows the user to conveniently perform a functional system check of their entire safety system. This signal
output simulation also aids the user in performing troubleshooting of signal wiring problems.
From the “Signal Output Check” text scroll, hold the magnet over PGM1 or PGM2 until the “◄” prompt
appears and then hold continuously for an additional 10 seconds. Once initiated, the display will scroll
“Simulation Active” until the function is stopped. During simulation mode, the 4-20mA value will be
increased from 4.0mA to 20.0mA (in 1% of range increments at about a 1 second update rate) and then
decreased from 20.0mA to 4.0mA. The same simulation sequence is applied to the Modbus™ output gas
reading.
NOTE
: Signal Output Check stays active indefinitely until the user stops the function. There is
no automatic timeout for this feature.
To end simulation mode, hold magnet over PGM1 or PGM2 for 3 seconds. The display will either move to
the prior menu item or move to the next menu item respectively.
Move to another menu item by executing a momentary hold, or, return to Normal Operation via automatic
timeout of about 15 seconds.
3.5.8
Restore Factory Defaults
Restore Factory Defaults
is used to clear current user configuration and calibration data from memory
and revert to factory default values. This may be required if the settings have been configured improperly
and a known reference point needs to be re-established to correct the problem.
NOTE
: “Restoring Factory Defaults” should only be used when absolutely necessary. All
previously existing configurational inputs will have to be re-entered if this function is executed.
A full 10-second magnet hold on PGM 2 is required to execute this function.
From the “Restore Defaults” text scroll, hold the programming magnet over PGM2 until the “◄” prompt
appears and continue to hold 10 seconds. The display will scroll “Restoring Defaults”, and then will revert
to the “Restore Defaults” text scroll.
Move to another menu item by executing a momentary hold, or, return to Normal Operation via automatic
timeout of about 15 seconds (the display will scroll “Restore Defaults” 4 times and then return to Normal
Operation).
Following the execution of “
Restore Defaults
”, the OLCT 700/710 TP will revert to its factory default
settings. The default settings are:
➢
Serial ID = 01. The Serial ID must be set appropriately by the operator (3.5.5)
NOTE
: The following must be performed in order before the detector can be placed in
operation.
➢
Range = 100ppm. Range must be set appropriately by the operator (3.5.4)
➢
AutoSpan Level = 25ppm. AutoSpan level must be set appropriately by the operator (3.5.3)
➢
Heater Power: Heater Power settings are lost and “Set Heater Power” (3.5.6) must be performed before
“AutoSpan”
➢
AutoSpan: AutoSpan Settings are lost and a successful “AutoSpan” must be performed before placing
the Detector into operation (3.4)
