9.2.2 When the compressor serves a single ice generator
9.2.3 Automatic starting and stopping
Ice production can be controlled by a clock. The start time is estimated according to the capacity of the ice bin (500
Kg of ice approx.per cubic meter) and the hourly production rate of the machine.
Important
In order to avoid short cycles that could damage your GENEGLACE, the ice level detector
switch must be associated with manual or time-delayed resetting.
The electro-mechanical ice level detector (a blade driven by a micro-motor) is the most commonly used. In order to
avoid short cycles, also use the terminal box 534004 requiring manual resetting or 534005 permitting time-delayed
resetting T2.
If the ice level detector or the clock trip, the solenoid valve and the water pump stop immediately while the reamer
continues to rotate for 3 minutes.
When this safety device is reset, the start up procedure is repeated as when starting.
Electrical sequences
When starting the ice generator, the compressor, the liquid feed solenoid valve, water pump and reamer begin
working simultaneously. If the condensing unit is outside there may be a delay of a few seconds before the reamer
and the pump start. (This is to ensure that at least 3/4 of the height of the generator is frozen at the start). On the
diagrams according to T1 a question mark has (?), this suggests that it is not always necessary to install it, if the
condensation unit is near the generator.
