10.22 fan set point (FSP)
The table below details the fan set point (FSP) parameter.
display
description
Prevents excessive condensation on the evaporator in environments where warm, and presumed
humid, air is present by operating the evaporator fan.
If the fan set point (FSP) temperature is exceeded, the evaporator fan running continuously even if the
door is opened.
On reaching set point (SP) temperature, the evaporator fan switches off during door openings.
considerations
Not related to fan cycle on (FCO) or fan cycle off (FCF).
Not used with OFCfirmware or the ems25
+
range 01 to 30ºC (33 to 86ºF)
global default 15ºC (59ºF)
10.23 condenser high temperature (Ht)
The table below details the condenser high temperature (Ht) parameter.
display
description
Defines the maximum temperature measured in the refrigeration system by
monitoring the condenser sensor.
On reaching the condenser high temperature (Ht), the ems controller disables
the compressor and activates an alarm.
considerations
1. Is not used with CO2 (R744) coolers.
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.
10.24 uninterrupted pull down (IPd)
The table below details the uninterrupted pull down (IPd) 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 (SP) temperature.
During this time, defrost cycles do not occur.
considerations Must be set as follows:
ems25+ and ems25advanced / General Use
