10. Operating and Monitoring Systems 10.
Sight-glass, still:
For observing the distillation process.
Overfill sensor, distillation:
Stops the pumping process when the filling
amount has been reached.
Sight-glass, inlet to water separator:
For observing the condensate feed from
distillation.
Limit switches:
All maintenance openings are protected with
limit switches.
Sight-glass, refrigeration unit:
For checking whether the cooling agent is free
of bubbles during the reduction phase
Green and red lamps:
Shows whether the distillation residues can be
drained.
Cooling water regulator, refrigeration unit:
You can set the condensation pressure in the
refrigeration unit here.
Manual valve, distillation steam:
For steam reduction
Cooling water regulator, distillation:
Regulates the cooling water flow (setting of the
cooling water temperature at drain
approximately +45 °C/113 °F)
Low cooling water level switch:
Monitors the cooling water supply.
Set to 1 bar (14.5 psi.)
Low pressure gauge (refrigerating):
For checking the evaporation pressure.
High pressure gauge (refrigerating):
For checking the condensation pressure.
Safety temperature limiter after cooler:
Cuts off all machine functions.
Call service technician.
High pressure control (refrigerating):
Switches the system to the malfunction state if
there is overpressure
Low pressure control (refrigerating):
Switches the system to the malfunction state if
there is not enough cooling agent
Thermal sensor, aftercooler:
Monitors the aftercooler temperature and
switches the machine off when the temperature
exceeds 30° C/86° F?
Thermal sensor, cage housing outlet:
Monitors the temperature at the air outlet
Thermal sensor, solvent:
Monitors the solvent temperature.
Low air pressure switch:
Monitors the compressed air supply. Set to 4
bar (58 psi)
Drying time controller:
Extends the drying time, depending on the type
and amount of garments
Pressure gauge, compressed air:
You can read off the required operating
pressure (6 bar/87 psi) on the pressure gauge
Sensor, water-sensitive:
Controls the draining of the process water
Thermal sensor, distillation:
Cuts off the distillation heater.
Sensor, low level:
Regulates the detergent solution level.
Thermal sensor, distillation condenser:
Monitors the solvent temperature.
Sensor, high level:
Regulates the detergent solution level.
Operating material thermal sensor, vacuum
pump:
Monitors the operating material temperature
