Halogen Gas Monitor – Multi Zone
44 Instruction 3015-5074
Intake Manifolds
Up to three additional intake manifolds (P/N 3015-5171 & 3015-3411) can be installed in the HGM-MZ to
increase the total capacity to 16 zones. Each manifold requires a sample line end filter for each of the 4
zones.
Please follow the instructions provided to install the manifolds. Then follow the instructions earlier in this
manual to install the air lines and complete the zone programming steps. The HGM-MZ setup must also be
updated to recognize the new zones.
4–20 mAdc Interface Board
The optional 4–20 mAdc Interface Board (P/N 3015-5152) allows the operator to take advantage of the
current loop interfaces provided for connection of external devices to the HGM-MZ. The interface board plugs
into the sockets provided on the valve/pump drive PCB, and the external devices are then cabled to the HGM-
MZ as described earlier in this manual.
