SYSTEM DRAINS - E & I SERIES - Each of the two (2) drain controls can be programmed to be
either a ‘TIMED’ or ‘DEMAND’ drains.
•
If Timed is selected, the drain will activate to the ‘Interval’ time setting for the period of time
indicated in the ‘Duration’ time setting.
• If Demand is selected, the drain will operate for the period of time indicated in the ‘Duration’
time setting, when a drain input signal is sensed from the demand drain float. A DRAIN FAULT
Alarm can occur if float does not respond as expected. When an fault is detected, the drain
solenoid will be ‘pulsed’ for ten minutes in an attempt to clear the faulted drain.
• The ‘Auto Test’ feature will operate the drain for the period of time indicated in the Duration
setting at the specified Interval. This feature is intended to prevent sediment buildup by activat-
ing the drain periodically and ‘blowing out’ any possible debris.
