Optional Accessories
Intake Manifolds
Up to three additional intake manifolds (P/N 3015-3419 & 3015-3411) can be installed in the HGM300 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 HGM300 setup must also be
updated to recognize the new zones.
4–20 mAdc Interface Board
The optional 4–20 mAdc Interface Board (P/N 3015-3133) allows the operator to take advantage of the
current loop interfaces provided for connection of external devices to the HGM300. The interface board plugs
into the socket provided on the main circuit board, and the external devices are then cabled to the HGM300
as described earlier in this manual.
