Elstat EMS-55-R User Manual

20
Sr
Stand-by restart. To ensure that the product is at the correct temperature
when the outlet opens, the EMS will switch to operational mode before
hand. This parameter sets this period. Must be set to a multiple of 30.
Ct
Refrigeration System Failure. This parameter sets the maximum continuous
compressor run time without the set point being reached. If the set point
temperature is not reached then the EMS will switch off the refrigeration
system and give a warning.
CF
The EMS can be set to display the temperature in either
o
C or
o
F
SSP
Stand-by set point. This value is added to the operational set point to give
the cut out temperature during stand by.
Sd
Stand-by differential. This parameter, when added to the operational and
standby set point, will give the cut in temperature, when the EMS is in
standby.
IPd
Uninterrupted Pull Down. When the temperature in the cabinet exceeds the
value set in this parameter the EMS will automatically perform an
uninterrupted pull-down. This means that no defrost cycle will be performed
and is to ensure that after a re-load the temperature of the product is
brought down as quickly as possible.
Dtt
Freeze up protection. If the appliance probe temperature drops below the
value set in this parameter then the EMS will inhibit the refrigeration system
until the temperature rises above the set point.This sets the activation
temperature for freeze up protection mode.
DE
Defrost intervals. This parameter sets the period between defrost cycles.
Dd
Defrost duration. This parameter sets the maximum time a defrost cycle can
be.
Dt
Defrost termination. When the temperature in the cabinet rises above the
value set in this parameter then the EMS will terminate the defrost cycle.
FCO
Fan cycle ON time. During the off cycle of the compressor, the evaporator
fan will cycle. This parameter sets the fan ON time.
FCF
Fan cycle OFF time. As above but for the OFF time.
FSP
Fan Set Point. If the cabinet temperature rises above the value set in this
parameter then the evaporator fan run continuously even if the door is
opened. Once the set point has been reached, the fan will then switch off
during door openings.
HT
High Temperature. This parameter sets the maximum allowable
temperature of the discharge line.
D2
Display stability. This should not be altered for normal operation.
HI
High Voltage. The EMS monitors the mains line voltage for fluctuation. This
parameter sets the maximum limit for over voltage. (see table)
LO
As above but for the minimum limit for under voltage. (see table)
B0
Buzzer enable/disable.
B1
Buzzer duration. If the cabinet door is left open then the buzzer will sound
for this period of time before the EMS disables the refrigeration system.
AD
Alarm Delay. This sets the delay between a door open alarm occurring and
the buzzer activating.
AF
Activity Frequency
This parameter sets the number of door openings/motion counts to signal
an active 30 minute period. If the is set to 3 then the EMS will automatically
learn whether the cabinet is situated in a low, medium or high traffic
location.
PER
Perishable mode. This allows the EMS to keep the operational set point and
differential during standby periods.
