1. Commissioning
Connect the heating plate via the 5 -pole flat plug connector to the
controller unit.
Warning: Make sure that there are no combustible objects in the vicinity
of the heating plate.
Check that the mains voltage corre sponds to the nominal value stated on
the type specification label. When you are sure that the mains voltage is
correct, connect the controller unit to the mains voltage. The changeover
switch for set point I actual temperature display should be set to "SET
POINT". Switch-on the control unit at its mains switch and set the
desired
temperature on the rotary potentiometer control. The red spot to the
right of the display digits lights up. This red spot indicates the
temperature controller action. Continuous i llumination means that the
actual temperature is below the set point temperature, that is the system
is heating-up. Flashing of the red spot means that the actual temperature
agrees with the set point temperature, that is the system is now
operating in the controlled temperature mode. When the red spot is not
lit, this means that the actual temperature lies above the set point
temperature. Move the changeover switch to the setting "ACTUAL". The
digital display now reads the actual temperature of the heating plate.
Equi-potential bonding
The various circuit elements of the 3. 5 mm jack bush make 4 variations
possible:
Hard-grounded: No plug (delivery form)
Equipotential bonding: With plug, equalizer at center contact (impedance
0 Ohms)
Potential free: With plug
