Working with Gas Alarms

Functional Overview

If the refrigerant level in the area being monitored exceeds its preset Leak, Spill, or Evacuate Alarm level (Page 17), the HGMSZ will detect this alarm condition and turn ON the front panel ALARM light. Additionally, an external alarm device may activate and the monitor’s internal audible alarm may sound if those features have been enabled (Pages 10 & 17).

Clearing / Silencing a Gas Alarm

Once the gas-alarm circuit has been triggered all alarm indicators remain turned ON, even after the detected gas level returns to normal. Press the SILENCE button to clear all gas-alarm indicators after the cause of the alarm has been cleared and the detected gas level has dropped below all alarm levels.

Pressing the SILENCE button while a gas-alarm condition still exists causes the internal audible alarm and all external alarm devices that are connected to the alarm relays to turn OFF for a period of time as set by the SILENCE function (Page 16). The front panel ALARM light remains ON, however, as an indication that an alarm condition still exists, but will automatically turn OFF once the gas level returns to normal. The alarm circuit will reactivate at the end of the silence period if the detected gas level is still above an alarm level.

Viewing the Gas Alarm Log

From the Data Display screen, use the Keypad buttons to place the arrow (>) on the display next to the ALARMS function. Then press ENTER to display the alarm log.

The alarm log shows the type of alarm (LEAK, SPILL, or EVAC), plus the date and time it occurred. If CLEAR is displayed, this indicates that an alarm was acknowledged at the date and time shown.

Immediately after selecting the ALARMS function, the most recent alarm event is displayed. In the example below, record #03 shows that a Spill Alarm occurred on 11/10/03 at 15:06. Note that if more than 30 alarm events have occurred, then the newest event overwrites the oldest.

Note that the Alarm Log can be cleared as described in Section Clearing the Stored PPM Log, Alarms & Faults Data on Page 20.

Working with System Faults

Functional Overview

If a system malfunction occurs (see Fault Code list on Page 19), the HGMSZ will detect the problem and turn ON the front panel SYSTEM FAULT light. Additionally, an external alarm device may activate and the monitor’s internal audible alarm may sound if those features have been enabled (Pages 10 & 17).

Clearing / Silencing a Fault Alarm

The SYSTEM FAULT light and all other fault indicators will automatically turn OFF after the cause of the fault has been eliminated.

Pressing the SILENCE button while a fault-alarm condition still exists causes the internal audible alarm and the external alarm device that is connected to the fault relay to turn OFF for a period of time as set by the SILENCE function (Page 16). The front panel SYSTEM FAULT light remains ON, however, as a reminder that a fault condition still exists. The alarm circuit will reactivate at the end of the silence period if the cause of the fault condition has not been corrected. The SYSTEM FAULT light will automatically turn OFF once the fault has been cleared.
