MGS-401 Final Installation Check
4.3.1
As a final check, ensure that all wiring and terminal blocks are secured. Ensure that none of the wires in
any of the terminations have any strands of wire that could be potential short circuits. Carefully remove
any of the slack from cable(s) through the ½” NPT cable fittings or 15mm cable glands.
Replace the rubber gasket and lid onto the instrument base. Using a 5/32″ (4 mm) hex key / Allen wrench
(not included), secure the lid by tightening the (6) Hex Head screws in and ‘X’ pattern from top left to lower
right, upper right to lower left and then the remaining center top and bottom screws. Torque all screws
to 15 to 20 lbf in (1.5 to 2.0 Nm.).
5. Power Up
Once the MGS-401 Entrance Monitor has properly wired and configured and the lid is installed, the power can
be turned on at the circuit break or disconnect.
1. Once powered up the MGS-401 will attempt to ‘discover’ all the MGS Gas Detectors that it is
configured to monitor, up to (4). Once discovered on the network each gas detector will show
‘Warm Up’ in the upper right of the gas detector quadrant. This will change to ‘Active’ once the gas
detectors have completed their warmup procedure. Some gas detectors may take up to a few
minutes to complete the warm-up cycle.
2. If one gas detector is configured to the MGS-401 the entire LCD screen will be populated as shown
below. If 2-4 gas detectors are configured to the MGS-401 the LCD screen will be populated in
quadrants. If only 2-3 gas detectors are configured, then the remaining quadrants will show
‘Inactive’.
