NMC-PRO Installation Manual

• Delta Pressure Reiteration: Number of consecutive filter flushing cycles triggered by the Delta Pressure that
can take place without any breaks, before the NMC-Pro will generate an alarm indicating that the Delta
pressure sensor is defective. The NMC-Pro will than ignore the Delta Pressure and will continue flushing
according to the set Time Between Flushing only, until the alarm is reset.
• Dwell Time Main Filter Valve (mm:ss): Define for how much time the main filter valve must be on before the
filter flushing cycle is started. This output is typically used to control a pressure-sustaining valve or to start a
booster pump.
5.9 Cooling
The Cooling/Humidification program is used to keep the temperature below a set value and/or the humidity above a
set value. Each program can be set to maintain temperature or humidity as its first priority.
Five Cooling programs are available with two periods in each program. The periods can be defined to overlap, thus
creating “dynamic” cooling or humidification.
Different temperature and humidity sensors can be connected to each program.
The Status can be defined as Cooling or Humidification, the aim of the status field is to help the user to understand the
process that should take place by placing the related set point first (i.e. above t° when the status is cooling OR bellow
RH when the status is Humidification)
Note: There are a few steps that should be defined prior to this screen: see Cooling Configuration.
• Program: Choose the required program 1 to 8, press ENTER to confirm.
• Status: define whether the program’s first priority is maintaining temperature or humidity.
• Cooling: the program’s priority is temperature. If the two periods are overlapping and there are different
settings in each period, dynamic cooling will take place.
Example:
• Settings:
Period 1 is set between 08:00 to 16:00, The cooling process should work above temperature of 30
o
C
and Below RH of 80%.
Period 2 is set between 08:00 to 16:00, The cooling process should work above temperature of 40
o
C
and Below RH of 80%
On time is fixed to 30 sec in both periods.
Off time is 3:00 minutes which relates to the lowest temperature setting (30°C)
Off time is 1:00 minute which relates to the highest temperature setting (40°C)
Scenarios:
• Time is 10:00, the measured temperature is 35
o
C and the measured relative humidity is 65%, the cooling
valve will be open for 30 seconds and close for 2:00 minutes in a continuous cycle.
• Time is 12:00, the measured temperature is 30
o
C and the measured relative humidity is 65%, the cooling
valve will be open for 30 seconds and close for 3:00 minutes in a continuous cycle.
• Time is 14:00, the measured temperature is 40
o
C and the measured relative humidity is 50%, the cooling
valve will be open for 30 seconds and close for 1:00 minutes in a continuous cycle.
• Time is 15:00, the measured temperature is 35
o
C and the measured relative humidity is 85%, the cooling
valve will not be open since the measured relative humidity is above the maximum allowed (80%).
