3.19 Monitoring the Water Flow Rate
The water connections are located at the front of the system underneath the
cooling zone.
The following conditions must be fulfilled in order to be able to monitor the
water flow rate:
• The system and the conveyor drive unit must be switched on.
• All emergency-off switches have to be unlocked in order that the water cir-
cuit has its flow again.
• The external water circuit must be connected.

external water circuit
The white marking at the
indicator must lie within the
maximum range of 8.

Fig. 3-31 Coolant Water Regulation
A)Coolant water regulator
The temperature of the coolant
water is regulated here.
The water flow rate is increased if
temperature needs to be
reduced, and the water flow rate
is reduced if temperature needs
to be increased.
B) Pressure controller
This controller checks the water
flow and triggers the alarm „water
pressure too low“ (if necessary).
