3.3.2. Interconnecting cables
On request, Honeywell can provide a wiring diagram showing all the power cords and
other interconnecting cables in the ACM 150 monitor and the connection points for each
cable. Refer to this diagram to determine which cord to unplug when removing power from
a specific pump or subassembly. Also, insert plugs into their receptacles, as shown on the
wiring diagram, when power is restored to a pump or subassembly.
NOTE
A 24 Vdc signal from the Sample Valve Control Panel goes to the Power
Distribution Panel at P1. This controls the Secondary Pump, turning on the power
when the inadequate vacuum is sensed. To change back to the Primary Pump,
switch the ACM 150 monitor from automatic to manual and back to automatic using
the Diagnostic menu.
3.4.
Air sampling system
3.4.1. ACM 150 flow cycles
The ACM 150 monitor is designed to move air samples from one area to the next as
quickly and efficiently as possible while ensuring that each sample is fresh and
representative of the air in the sampled area when analyzed. The Cycle Valves are shown
in Figure 9.
The ACM 150 monitor does this by sampling each area in four steps or flow cycles with
the following valves opened:
• Evacuate: S1 and S6
• Surge: S2 and S6
• Fill: S2
• Analyze: S1
