Starting The Glaciator X-Stream - JEM Glaciator X-stream User Manual

If the ICE switch is ON, but the compressor is not running, the system is in
power save mode. It will restart when the smoke system is fired (from any
signal source) or when the ice switch is cycled. The starting delay will
depend on the current evaporator temperature, but will not prevent
immediate production of fog at full output.
To check the status of the refrigeration system at any time, use the ICE
menu on the right hand display panel. The left hand panel will now display
the name of the value, while the right hand display will show the
temperature. Use the scroll keys on the right hand display to move
through the available values.
Evaporator fan control
When the current firing cycle is over, the evaporator fan will run at
maximum speed for 3 seconds to clear the remaining smoke from the
evaporator compartment. To allow for machines with ducting on the
output, a special extended run mode can be selected. By setting the
special function switch 1 (s1) to ON (down), a 6 second run-on time for
the evaporator fan can be selected. Remember that the density setting for
ducting is 'Lo', since this gives the greatest fan speed for any given fog
output level.
The evaporator fan may run at other times to assist in the control of the
refrigeration system.
Condenser temperature control
The radial blowers used to cool the condenser unit are powered from a 2
speed relay which is controlled by the machine's microprocessor. The
speed of the fans is determined by the temperature of the condenser unit
and the thermal load on the evaporator. The control software uses a timer
to prevent short-cycling of the speed controller. Under almost all ambient
conditions, the fans should run at low speed when the machine is idling,
but when fired, the system will switch to high speed. The high speed
running will continue after the end of the current firing cycle, and is timed
according to the temperature of the condenser unit.
