impaired.

No user serviceable parts are inside of this Controller.
Refer servicing to your dealer.

TheLIQUI-SENSE Controllermustbe positioned soleak­ing liquid will not enter the rear power connectors. Use
of a power line with a Ground Fault Interrupt (GFI) is
recommended.

Use with caustic liquids not compatible with detector
materials voids warranty.

INTRODUCTION

The LIQUI-SENSE 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 77096-00
LIQUI-SENSE Controller operates from 115V AC and the Model 77096-05
operatesfrom230VAC.Whenanalarm condition issensed on eitherchannel,
the LIQUI-SENSE 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 audiblealarm is enabled.

• Provide a contact closure output that can be used to activate an

Environment Monitor for automatically telephoning the user of the f ailure ,
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 LIQUI-SENSE Detector Model 77095-00 (detector with cable) or Model
77095-01 (detector without cable) is used to sense leaks in pump heads
resultingfrom ruptures of thetubing.This detectoris notsuppliedwith theunit
and must be ordered separately. (See ACCESSORIES.)

APPLICATIONS

The LIQUI-SENSE Controller and LIQUI-SENSE Detector can be used with
a wide variety of different pump systems for leak detection. The alarm
controller has two inputs. These can both be used with LIQUI-SENSE
Detectors, or one input can be used with a LIQUI-SENSE Detector and the
second inputused with other typedetectors such asa liquidleveldetector for
determininghigh orlowlevelsina container.Figures 1through5show various
suggested detector arrangements in different pump systems. Tubing is
omitted for clarity.

DESCRIPTION

The LIQUI-SENSE Controller, shown in Figure 6, is used to monitor various
liquid detector devices. When an alarm condition is detected, the controller
deactivates the rear panel MAIN OUTPUT power connector and supplies
power to the AUXILIARY OUTPUT power connector .Also, when the alarm
condition is detected, a contact closure output is provided at the rear panel
CONTACT CLOSURE OUTPUT connector (a 1/8-inch phone-type
connector) for activating remote devices such as an Environment Monitor or
a second pump drive. The fault condition is indicated by a red ALARM ON
indicator on the front panel and by an audible alarm (unless the ALARM
AUDIBLE switchhas been set to OFF).

Figure6. LIQUI-SENSE Controller (Alarm Module)

The MAIN and AUXILIARY connectors, shown in Figures 7 and 8, are used
to connect to external devices such as pumps. The pump connected to the
MAIN OUTPUTconnector willoperate whenno alarmcondition exists.When
an alarm condition is detected, power to the MAIN OUTPUT connector is
turned off and power isapplied tothe AUXILIARY OUTPUT connector.Thus,
if nopump is connectedto the AUXILIARY OUTPUTconnector, pumpingwill
cease. If a pump is connected to the AUXILIARY OUTPUT connector, that
pump will be turned on. The switch over occurs within one second after
detection of an alarm condition.
