INSTRUCTIONS
Triac controller for proportional control of
electric heating, with min- / max- limiting
function
PULSER-M is a complete proportional controller for electric heating.
It has automatic voltage adjustment and can be used with either
built-in sensor or external sensor. PULSER-M pulses the whole load
On - Off. The ratio between On-time and Off-time is varied 0 - 100%
to suit the prevailing heat demand. The current is always switched
at zero phase angle to prevent RFI. It also has an input for a
separate sensor for maximum or minimum limiting the supply air
temperature during room temperature control.
PULSER-M is only intended for electric heating control. The control
principle makes it unsuitable for motor- or lighting control.
PULSER-M cannot control 3-phase loads.
Installation
Remove the front. The locking screw is be-hind the set-point knob.
Mount PULSER-M vertically, with the cooling flange at the top. Use
screws with a maximum head diameter of 5.5mm.
If PULSER-M is to be used with the internal sensor, mount it
approx. 5ft above floor level at a location with a representative
temperature. The air must be able to circulate freely around the
PULSER-M without disturbances from doors, furniture etc.
N.B. PULSER-M emits approx. 20W of heat which must be
dissipated.
N.B. Maximum ambient temperature at full load is 30°C.
Ambient temperature 0 - 30°C non-condensing.
Degree of protection: IP20.
Wiring
Supply voltage (fig 1)
Terminals 1 and 2. Not polarity sensitive.
Supply voltage: 200 - 415V AC, 50 - 60 Hz with automatic voltage
adjustment.
Maximum current 16A.
N.B. The supply voltage to PULSER-M should be wired via an all-
pole switch with a minimum contact gap of 3mm.
N.B. The cooling flange is live.
Load (fig 1) Terminals 3 and 4.
Resistive single- or two-phase heater
Maximum load: 3680W at 230V (16A)
6400W at 400V (16A)
Minimum load: 230W at 230V (1A)
400W at 400V (1A)
External sensor and set-point (figs 2 - 6)
Terminals G and G. Not polarity sensitive.
INSTRUCTIONS
N.B. When using external set-point and/or sensor the equivalent
function in the PULSER-M must be disabled. This is done
by setting the DIP-switches to the right of the terminal strip
according to the relevant figure.
Night set-back (fig 7) Terminal K and K.
Potential-free closure will give a night set-back of 0 - 10K.
Settable with a potentiometer in the PULSER-M.
Minimum/maximum limit (figs 8 and 9)
Terminals M and M. Not polarity sensitive.
Choose function with the switches next to the MM terminals. Set
the limiting temperature on the min/max-potentiometer next to
the MM terminals. Fully counter-clockwise equals the low end
temperature of the sensor and fully clockwise equals the upper
end temperature. 5K per division.
N.B. The PULSER-M sensors have high potential compared to
neutral and earth (>200V). Thus, wiring and installation of
the sensors must comply with local codes for line voltage
installations.
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 tempera-
ture 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
disturbing the position of the rings. Replace the knob and check
the result. Make fine adjustments if necessary.
