INSTRUCTION
Start-up and fault finding
1. Check that all wiring is correct.
2. Measure the resistance between terminals 3 and 4: At 230V:
14.4? <R<230? .
At 400V: 25? <R<400? .
3. Connect supply voltage and turn the setpoint knob to the
maximum value. The LED in the side of the PULSER/D should
be continuously On or pulse On/Off with longer and longer On-
time and eventually be continuously On.Turn the setpoint to the
minimum value. The LED in the side of the PULSER/D should
be continuously Of or pulse On/Off with longer and longer Off-
time and eventually be continuously Off. At a certain position
(within the proportional band) the LED will pulse On-Off as the
PULSER/D 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.
Something wrong?
4. Shut off power and remove wiring to external sensor ( and
setpoint if any). Measure the resistance of the sensor and
setpoint separately. The potentiometer resistance varies 0- 5k?
between the lower and upper end-point. The sensor resistance
varies between 10k? and 15k? between the upper and lower
ends of the sensor temperature range. I.e. a TG-K330 has 15k?
at 0°C and 10k? at 30°C. The resistance changes by 167? /°C.
5. Leave the sensor terminals G1, G2, G3 unconnected. Switch on
power.
PULSER/D 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.
If OK the PULSER/D is probably faulty.
If the LED lights up but no current is flowing: Recheck the heater
resistance as above.
If OK the PULSER/D is probably faulty.
INSTRUCTIONS
6. Shut off power and short-circuit the sensor input G1-G2 or
G1 - G3. Switch on power again.
PULSER/D 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/D is faulty.
If the LED is lit, recheck the shorting of the sensor input
terminals. If OK the PULSER/D is faulty.
7. If everything is OK this far the PULSER/D and the sensor/
setpoint are OK.
Shut off power, remove the wire strap from the the sensor
input terminals and reconnect external sensor (and setpoint
if any). Connect power.
