CAUTION!
Composite point sampling may expose employees to hazardous conditions by
lowering the gas detection capability. Use Composite Points only if the rate of
scan must be increased. The following rules apply and must be followed:
1. Group only the sample areas that are in close proximity to avoid combining
long and short tube runs, which may cause an imbalance in the composite
mixture.
2. Group points which have identical Single Point Configurations, i.e. the same
method with the same active gases and the same Alarm 1 and Alarm 2 set
points.
MISE EN GARDE!
Point Composite échantillonnage peut exposer les employés à des conditions
dangereuses par l'abaissement de la capacité de détection de gaz . Utilisez
Points composites que si le taux de balayage doit être augmentée. Les règles
suivantes sont applicables et doivent être suivies :
1. Groupe seules les zones de l'échantillon qui sont à proximité d'éviter de
combiner longues et de tubes courts tirages , ce qui peut causer un
déséquilibre dans le composite mélange.
2. Points Groupe qui ont identiques Configurations point unique, à savoir le
même méthode avec les mêmes gaz actives et la même Alarmes 1 et 2

Programmable relays
The ACM 150 monitor has 80 programmable relay outputs. The functions and uses
of the relays are described in section
relays have a default setup that controls their program until that setup is changed.
Reviewing the programmable relays
Relay 1 is preassigned to point 1. It activates when the Alarm 1 level set point is
exceeded for 'all gases'. Relay 2 is preassigned to point 2 at the warn level. This
progression continues through relay 40 and point 40.
Relays 41-80 follow the same progression, i.e. relays 41-80 are preassigned to points
1-40. Relays 41-80 activate at the Alarm 2 level set point for all gases.
"All gases" applies to the gases actively monitored at that point. If one or more of
these gases exceeds its Alarm 1 set point, relay 1 would activate. If any of these
gases exceeds its Alarm 2 set point, relay 41 would activate.
