Introduction - Barnant Company 877-9605 Operating Manual

The LIQUID-SENSOR Controller is a two-channel alarm system used to
sense liquid leaks using a specially designed detector or used with other
liquid detectors such as high or low liquid level detectors. The Model
877-9600 LIQUID-SENSOR Controller operates from 115V AC and the
Model 877-9605 operates from 230V AC. When an alarm condition is sensed
on either channel, the LIQUID-SENSOR Controller can perform the following
actions:
• Disconnect power to a pump drive.
• Activate an auxiliary pump drive to resume pumping through a second
pump drive.
• Activate the front panel red ALARM ON indicator.
• Sound an audible alarm if the audible alarm is enabled.
• Provide a contact closure output that can be used to activate an
Environment Monitor for automatically telephoning the user of the failure,
or to activate any other device that operates from a contact closure
input. The contact closure may also be used to operate shut-off or
switchable valves to redirect flow.
The LIQUID-PAD Detector Model 877-9500 (detector with cable) or Model
877-9501 (detector without cable) is used to sense leaks in pump heads
resulting from ruptures of the tubing. This detector is not supplied with the unit
and must be ordered separately. (See ACCESSORIES.)
