The
EPC-100 Conventional Control System
is an all electronic control system that
controls two compressors or one
compressor and one unloader, a maximum of
three condenser fans, a single
off-time/electric defrost circuit, the case
temperature of a single system, and the
monitoring and alarming of all monitored
pressures and temperatures. The system is
menu-driven, and the keypad allows the
user to make changes quickly by answering
the prompted questions.
-
Compressor
Control - it can
control the compressors and the
unloader by suction pressure
control, case temperature, or
suction pressure reset
-
Condenser
Control - it can
control a condenser fan bank with
up to 3 fan stages or speeds. The
fans can be controlled based upon
head pressure, liquid line
temperature, or when the
compressor is running
-
Defrost
- it can operate a single defrost
circuit in off-time or electric
cycles. The defrost schedule can
include up to 12 cycles, a
pump-down cycle, and a drip
cycle. Defrosts can be terminated
by temperature or suction
pressure
-
Temperature Control
- The EPC-100 will cycle the Liquid Line Solenoid
pump down the compressor based upon a Temperature
Control Setpoint and a Cut In - Cut Out
Differential. The EPC-100 will activate alarms
should the room temperature go below or above a the
temperature alarm limits.
-
Remote communication for
easy access
Memory Protection--The
EPC-100 uses the latest EEPROM and static
RAM technology to store configuration
data, operational settings, and the alarm
log. A power outage will not alter or
erase any stored data. The system clock
is battery backed and will retain the
time and date for up to 5 years without
power. The clock is Y2K compliant and
leap year compliant until year 2100.
GenCom Communications
Capability--With a MS-DOS or
Windows operating system based computer
and a modem, a user can monitor and
control several EPC-100 units from within
a store or from a remote location. This
option provides full accessibility to the
EPC-100's functions and keeps the user
aware of system alarms and operating
conditions.
