2.4 Machine Lockout
In general, the machine should be operated in AUTO mode in which
conditions are confirmed electronically. The ECM-100 terminal strip has
terminals available for linking other treatment equipment, such as a
softener, to the operation of the 23G machine or monitoring the status of
other equipment. The status of this equipment is indicated by Light-
Emitting Diode (LED) lights on the ECM-100. When operating in HAND
mode, it is the operator’s responsibility to ensure adequate feedwater
supply and storage tank capacity.
Lockouts are ignored in HAND mode, such as full tank level, etc. CIP
mode ignores temperature and pH alarms.
The Pretreatment Lockout input can be used in AUTO mode to shut down
the machine (all outputs turned off) when there is an interruption of
feedwater supply, such as when a pretreatment filter is backwashing. The
terminals for the Pretreatment Lockout on the ECM-100’s main strip look
for an “open” contact to shut down the machine and illuminate the blue
Pretreatment Lockout LED light.
