15.1 Water Circuit
Strainer
The strainer is included in the hose set and fitted outside the chiller in the water inlet line.
Temperature sensor
The temperature sensor detects the water inlet temperature which is displayed at the control and
operating unit.
Temperature limit values
The water temperatures in the water circuit are monitored by limit values. If the preset limit values
are exceeded or not reached, a general fault alarm is issued on the control panel.
Flow control switch
The flow control switch is fitted in the water inlet pipe and is designed to monitor the flow rate in the
water circuit. If the minimum flow rate is fallen short of, the pump is switched off.
15.2 Electrical System
Glass fibre cable
A 100m long glass fibre cable is available as an option. As standard the P030 Chiller communicates
with the COO via a glass fibre cable up to 50m in length.
Control cabinet heater
The control cabinet heater is installed for temperature stabilisation of the control cabinet inside
temperature versus the ambient temperature (condensation water formation) and for the purpose of
ensuring minimum temperatures for the switchgear and controlgear inside the control cabinet.
Outdoor installation and pump shutdown upon a general fault alarm
In the event of a general fault alarm, the pump is shut down by the controller. After the fault has
been eliminated and a Reset carried out at the controller, the pump is restarted. If the general fault
alarm was triggered by the preset temperature limit value causing the pump to be shut down it is
necessary to carry out a restart. The restart is effected after the „fault reset“ has been carried out by
means of the ON/OFF control switch. The limit value alarm will be suppressed for 30 min. The
pump starts operating and the water temperature can drop below the preset limit value.
15.3 Cooling Air Supply
Protective condenser grille with air filter element monitoring
The max. permissible degree of contamination of the air filter element is monitored by the
condensation pressure.. If the max. permissible pressure is exceeded, a warning message "Filter
contaminated" is displayed on the control and operating unit.
