2. Requires a condenser sensor.
3. To set the condenser high temperature
(Ht
), measure the
refrigeration system temperature when the condenser is 75% blocked.
4. To disable, set below 50ºC or 122ºF.
range
0.0 to 125ºC (32 to 257ºF)
global default
0.0ºC (32ºF) - disabled.

uninterrupted pull down (IPd)
The table below details the uninterrupted pull down (
I Pd
) parameter.
display
description
Defines the temperature that if exceeded starts an uninterrupted pull down, i.e. the ems controller
switches on the compressor and runs the compressor continuously until the product reaches the set
point (
S P
) temperature.
During this time, defrost cycles do not occur.
considerations
Must be set as follows:
l
Above the saving set point (
S S P
) plus saving differential
(
S d
) temperature.
l
Above the defrost termination (
dtd
) temperature.
range
0.0 to 30ºC (32 to 86ºF)
global default
20ºC (68ºF)
10.30
lights delay (Ld)
The table below details the lighst delay (
L d
) parameter.
display
description
Defines the delay to switch off the cooler lights after the ems controller switches to the
saving mode
.
considerations Must be set in multiples of 30.
range
0 to 120 minutes
global default
00 (no delay)
10.31
low voltage (LO)
The table below details the low voltage (
L O
) parameter.
display
description
Defines the minimum voltage allowed before switching off the compressor.
The low voltage (
L O
) values are approximations and not actual voltage readings (see table below).
considerations
1. Must not be used with an external voltage stabiliser
