TROUBLE SHOOTING
All Tamson products are well designed and carefully
tested before shipping. This will not fully prevent small
problems in the field. Following will help you to locate
commonly known problems and how to fix them. In case
of doubt please check your local dealer or Tamson
Instruments bv.
9.1
General
Bath malfunction
The motor is not running and electronics is dead
Check mains fuse
Motor is not running:
Probably the motor fuse is activated. Restart the
motor by pressing the motor fuse .
Check viscosity of the bath fluid. High viscosity will
activate the motor fuse.
Electrical defect. Motor capacitor defective.
Replace capacitor or contact local dealer or
Tamson Instruments bv.
Problems with set point
Heater LED is not burning, motor is turning and
temperature raises above set point:
Setpoint too near to room temperature
. Cooling of
the bath is needed
.
Temperature doesn’t reach set point, motor turns
fast:
Bath fluid evaporates too quick. Use other fluid.
Heater malfunctions:
Measure electric mains current. Current below 2
amps indicate a problem with the heating element.
Temperature not stable
Tune the bath at the set point temperature.
Difference between ambient and bath temperature
is too small (Applied power indication is below
8%). Use cooling coil
PID values
Unable to set PID values:
Check if ATUN has been set to on. PID values can
no longer be adjusted unless the ATUN value is
set to off. See 8.4 selecting parameters.
Readout / indicator
The temperature readout on the display does not
correspond to the temperature measured.
Check the PT100 sensor
Level indicator on frontpanel blinks.
Fluid level probably too low, check fluid level
Be aware that the fluid level always needs to be
higher than the heating element(s).
An heating element which partially operates above
the fluid (so partially exposed to air above the fluid
level) can get hot en may possibly ignite the fbath
fluid.
