INSTRUCTION
Setpoint range limiting
The setpoint range can be mechanically limited using the limiting
rings behind the setpoint knob.
Set the knob to a temperature within the desired limiting range. Pull
off the knob.
Loosen the screw locking the two rings. Rotate the blue ring so that
the protruding part is slightly lower than the lower temperature limit.
Use the markers on the bottom of the covers knob-cutout as an aid.
The markers are 5° apart.
In the same way set the red ring to a value slightly higher than the
upper limit temperature. Retighten the locking screw without distur-
bing the position of the rings.
Replace the knob and check the result. Make fine adjustments if
necessary.
Start-up and fault finding
N.B. Be careful when working in the PULSER. All internal
components including the cooling flange are at line voltage
potential.
Never leave the unit under power without the front cover on.
1. Check that all wiring is correct and that the sensor selector
switches are in the correct position.
2. Measure the resistance between terminals 3 and 4:
At 230V: 14.4Ω<R<230Ω. At 400V: 25Ω<R<400Ω.
3. Connect supply voltage and turn the setpoint knob to the
maximum value. The LED in the side of the PULSER should be
continuously on or pulse on/off with longer and longer ontime
and eventually be continuously on.Turn the setpoint to the
minimum value. The LED in the side of the PULSERshould be
continuously off or pulse on/off with longer and longer offtime
and eventually be continuously off. At a certain position (within
the proportional band) the LED will pulse On-Off as the PULSER
pulses current to the heater The pulse cycle period is approx. 60
seconds. Check with a clamp-on ammeter that current is flowing
to the heater.
INSTRUCTION
Something wrong?
4. Remove wiring to external sensor. The sensor resistance
varies between 10kΩ and 15kΩ between the upper and lower
ends of the sensor temperature range. The resistance
changes by 167Ω/°C.
5. Set both the sensor selector switches in the downwards
position but leave the sensor inputs G-G open. Switch the
voltage on.
PULSER should give full uninterrupted power and the LED
should be lit. Check with a clamp-on ammeter that current is
flowing to the heater.
If the LED is not lit and no current is flowing: Check that you
have power on terminals 1 and 2 and recheck the positions
of the sensor selector switches. If OK the PULSER is
probably faulty.
If the LED lights up but no current is flowing: Recheck the
heater resistance as above. If OK the PULSER is probably
faulty.
6. Shut off power and short-circuit the sensor input G-G but
leave the switches in the downwards position. Switch on
power again.
PULSER should not give out any power at all and the LED
should be extinguished. Check with a clamp-on ammeter that
no current is flowing to the heater.
If the LED is extinguished but current is flowing to the heater
the PULSER is faulty.
If the LED is lit, recheck the shorting of terminals G-G. If OK
the PULSER is faulty.
7. If everything OK this far the PULSER and the sensor/setpoint
are OK.
Shut off power, remove the wire strap from G-G and
reconnect external sensor/setpoint if any. Set the sensor
selector switches in their correct positions according to the
appropriate wiring diagram for the installation at hand.
Replace front cover and setpoint knob. Connect power.
