Program Features - Teledyne 700 IR Series Instruction Manual

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 IR will revert to its factory
default settings. The default settings are:
• Serial ID = 01. The Serial ID must be set appropriately by the operator (Section 3.5.6).
NOTE: The following must be performed in order before the detector can be placed in operation.
• AutoSpan Level = 50 %LEL. AutoSpan level must be set appropriately by the operator (Section
0).
• Gas Type = CH4. The Gas Type must be set appropriately by the operator (Section 3.5.4).
• Gas Factor = 1.0. The Cal Factor must be set appropriately by the operator (Section 0).
• Sensor Gain: Sensor gain settings are lost. Sensor Gain must be performed (Section 3.5.7).
• AutoZero: AutoZero Calibration Settings are lost. AutoZero must be performed (Section 3.4).
• AutoSpan: AutoSpan Calibration Settings are lost. AutoSpan must be performed (Section 3.4).

Program Features

Teledyne Oldham Simtronics OLCT 700/710 IR gas detectors incorporate a comprehensive set
of diagnostic features to achieve Fail-Safe Operation. These Operational features and Failsafe
Diagnostic features are detailed below.
3.6.1 Operational Features
Over-Range
When gas greater than the full-scale range is detected, the OLCT 700/710 display will
continuously flash the full-scale reading of 100. This designates an over-range condition. The 4-
20mA signal will report a 22mA output during this time.
In-Calibration Status
When the detector is engaged in AutoZero or AutoSpan calibration, the 4-20mA output signal is
taken to 2.0mA and the in-calibration Modbus™ Status Register bit 14 is set. This alerts the user
that the OLCT 700/710 is not in an active measurement mode. This feature also allows the user
to log the AutoZero and AutoSpan events via their master control system.
