h) Measurement and supervision:
➢Temperature of the reactivation air measured by the probe (ST1).
➢Process air temperature measured by the probe (ST0) after the pre-heating
battery BC1.
➢Process air temperature measured by the probe (ST3) after the pre-cooling
battery BF1.
➢Process air temperature measured by the probe (ST4) after the post-
cooling battery BF2.
➢Process air temperature measured by the probe (ST4) after the post-
heating battery BC2.
➢Synopsis of component operation screen.
➢Monitoring the proportional modulation of the BR (power delivered by the
reactivation battery BR).
➢Monitoring the power delivered by the pre-heating battery BC1.
➢Monitoring the power delivered by the pre-cooling battery BF1.
➢Monitoring the power delivered by the post-cooling battery BF2.
➢Monitoring the power delivered by the post-heating battery BC2.
➢Humidity measurements (relative, absolute, dew point or mixing ratio) and
temperature measuredby the probe SH1-ST2 to be installed in the process
air inlet or return.
➢Humidity and temperature measurements by the probe SH2-ST4 to be
installed in the dry air supply.
➢Monitoring humidity set point.
➢Monitoring maximum humidity alarm set point.
➢Minimum reactivation air flow of and rotor rotation.
i) Safety and alarms:
➢Timing at the disconnection of the humid-air motor fan and the gearmotor
for cooling the equipment.
➢Alarm and equipment shutdown due to lack of air in the reactivation.
➢Alarm and equipment shutdown due to lack of rotation of the desiccant
rotor.
➢Alarm and equipment shutdown due to triggering any motor thermal cut-off.
➢Alarm and equipment shutdown due to triggering electrical protective
devices of the heaters.
➢Alarm and heater shutdown due to excessive SSR temperature.
➢Alarm for blocked process and reactivation filters (if applicable).
➢Alarm and BR heater shutdown due to excessive reactivation temperature
as measured by probe ST1.
➢BC2 heater shutdown due to excessive temperature as measured by
operating thermostat TF3. To be reset manually.
