TROUBLE SHOOTING
8.1
Safety devices
The controller is equipped with a number of safety
devices which switch off the bath to prevent excessive
temperature rise or malfunction. The safety devices are
divided in mechanical and electronic parts. The
mechanical over-temperature safety thermostat is
located near the mains switch and consists of an
adjustable thermostat and a red arrow shaped lamp.
The desired temperature at which the bath should be
switched off can be set by turning the knob with a
screwdriver or a coin.
8.2
Over-temperature safety thermostat
When the thermostat is activated the entire bath is
switched-off (with the exception of the controller) the
red system error LED will light up. When the
temperature of the bath has been lowered with
approximately 20 degrees, the thermostat re-sets itself
automatically, however to continue normal operation the
bath has to be switched off and on again.
The thermostat can be adjusted as follows:
-Turn the thermostat fully clockwise.
-Heat the bath to its proper temperature. Be aware that
the safety thermostat is now only functioning at 270 °C.
-Turn the thermostat gently counter clockwise, until you
hear a “click”. Turn the knob approximately 20 to 30°
higher (clockwise). Switch the bath Off and On again.
The bath is ready to operate safely.
8.3
Error messages
There are two types of error messages:
-
Fatal
-
Non fatal
In case of a fatal error the bath will be switched off. If a
non fatal error exists the error will be repeated after
approximately 3 minutes.
8.4
Application errors
Besides the electronic errors reported on the display
there are also practical errors.
8.5
Bath temperature does not become stable
If the bath temperature does not stabilize after 45
minutes after set point has been reached the following
points might cause this problem:
·The operating temperature is around or below 30°C. To
stabilize the bath at a set-point temperature just above
the ambient temperature it is necessary to apply cooling
