MGC Pump User’s Manual
UM-MGC-P v1.06 10 of 19
Maintenance Notication- If maintenance notication is enabled, the detector will periodically ash the
maintenance LED. Otherwise, if the option is disabled, the detector will only show the maintenance text on the
display.
Pump Test- Will require the pump to be tested (block and unblock) on startup.
Dock Lock- Dock Lock prevents calibrations and bump tests without the use of the IR Link or the MGC Pump
Dock.
Latching Alarms- Latched alarms will hold the detector and its display in its peak alarm condition until the button
is pressed.
Auto-Zero- The detector can optionally zero the sensors with every power-up.
TWA Method- The algorithm used to calculate the TWA can be set to either an average over a moving window
(OSHA) or as a cumulative average (ACGIH).
TWA Interval- The TWA interval denes the time frame over which the long-term average is calculated. Default is
8 hours.
STEL Interval- The STEL interval denes the time frame over which the short-term average is calculated. Default is
15 minutes.
Sensor Enable/Disable- Individual sensors can be disabled. A disabled sensor is completely removed from the
detector’s display for sensor readings, alarm limits and calibrations.
Caution: A disabled sensor will not measure gas or detect alarm conditions.
Bump Interval- The bump interval controls how often the detector noties the user to bump test the sensors. The
interval can be individually adjusted for each sensor from 1 to 365 days. Default is N/A (disabled).
Calibration Interval- The calibration interval controls how often the detector noties the user to calibrate the
sensors. The interval can be individually adjusted for each sensor from 1 to 365 days (default is 365 days) except
for the pellistor sensor which can be adjusted from 1-180 days (default is 180 days).
Calibration Gas- When the detector is calibrated, it scales the sensor readings to match the concentrations of the
applied gases. The calibration gas concentrations can be adjusted to match the respective levels contained within
the gas bottle. Default is: 25ppm H
2
S, 100ppm CO, 18% O
2
and 50%LEL (2.5%vol CH
4
).
Language: The detector will display all of its text prompts in any of the following languages: English, German,
French, Spanish, Italian or Portuguese.
• Note: OL, Err and sensor icons remain the same for all languages.
