C 150 (E2) 06/2011 page 48/78
Actions:
•
Check that you have set the pressure on the pressure reducer at 2.0 bar / 29 psi above the ambient
air pressure, and that all the valves are open for the gas supply.
•
Where the CO
2
supply is a pressurized gas bottle, check that the bottle still contains sufficient CO
2
.
If necessary, replace the gas bottle.
•
Check whether the primary pressure is high enough at the central CO
2
supply.
•
Check that the gas tube has no damage, kinks, blockages or soiling.
•
Check when the gas filter was last replaced. Replace the gas filter every year to avoid it blocking.
A qualified service engineer should replace the gas filter.
•
If points 1 to 5 do not reveal the source of the fault, it may be that the unit is faulty. Please contact
BINDER Service.
The outlet pressure of the gas bottle must be 2.0 bar / 29 psi above the ambient pressure.
CAUTION
Excessive output pressure > 2.5 bar /
36 psi
.
Damage to the unit.
∅
Do NOT exceed the output pressure of 2.5 bar / 36 psi above the ambient pressure
¾ Before connection, check the output pressure on the pressure reducer of each bottle.
The recovery times of the gas concentrations inside the chamber following the door being opened, which
are indicated in the technical data (chap. 18.4), refer to a connection pressure of 2.0 bar /
29 psi . De-
creasing supply pressure down to the alarm point of 0.3 bar / 4.4 psi results in longer recovery times.
Check the pressure displays of your gas supply. If very short recovery times are required or the door is
opened frequently, replace the gas bottles promptly when the pressure decreases below 2.0 bar /
29 psi .
10.9 Temperature sensor failure
A sensor fault alarm display takes priority over all other operational displays and alarm signals on the
controller.
•
Immediate alarm
•
Visual display:
LED Upper Display, flashing
Alarm code Meaning
Failure of temperature sensor for interior heating:
interior heater is turned off
Failure of the safety controller's temperature sen-
sor: all heaters are turned off
Flashes
Failure of temperature sensor for door heating:
door heater is turned off
•
Audible alarm: buzzer (intermittent sound)
•
Switching the zero-voltage relay alarm output
Actions:
•
Turn off the C 150.
•
If necessary, clean and disinfect the C 150. Automatic sterilization is not possible with this fault.
