Explanation Of Error Messages - Primus I35/50 Programming Manual

4.6. EXPLANATION OF ERROR MESSAGES

IMPORTANT!
TECHNICAL REPAIRS OF IRONER CAN BE EXECUTED ONLY BY TECHNICIANS WITH APPROPRIATE
KNOWLEDGE OF THE MACHINE.
ERROR 1: TEMPERATURE OF IRONING ROLLER IS HIGHER THAN 200°C
Error is detected by temperature sensor. For higher safety the machine is equipped with separate safety
thermostat, which disconnects heating when temperature exceeds 210°C.
CAUSE:
1. Interruption of ironing when temperature of
ironing roller is high (180°C)
2. Failure of electrical installation
3. Interruption of temperature sensor
(displayed temperature is 255°C)
ERROR 2: TEMPERATURE OF IRONING ROLLER IS HIGHER THAN 80°C AND
THE ROLLER IS NOT ROTATING
Rotation of ironing roller is evaluated on the basis of signal from frequency inverter. If the roller stops due to
any cause (it means either on purpose, e.g. by the button for reverse operation, by pushing the crank or safety
bar, or due to failure), then after 5s the siren starts whistling to warn about danger – burning of ironing belts.
CAUSE:
1. Pressing the button for reverse operation
2. The crank for manual rotating of the roller was
pushed
3. The safety bar was pushed
4. Failure of drive
ERROR 3: OVERLOADING OF VENTILATOR(S) MOTOR(S)
The machine is equipped with one, and at length 250 and 320 cm with two ventilators for exhaust of
evaporated humidity, or combustion gases from the gas burner. In motor winding of every ventilator there is
placed bimetal that detects overheating of the winding.
CAUSE:
1. Mechanical failure of ventilator
2. Clogged exhaust pipeline
ERRORS 4 AND 5: SHORT CIRCUIT / INTERRUPTION OF TEMPERATURE SENSOR
Temperature sensor of ironing roller is pushed on the roller approximately in 1/3 of its length and it is
equipped with cable with silicone insulation, which withstands high temperatures of ironing roller without
problems. When the failure occurs, the sensor must be changed (repair is not possible).
ERROR 6: FAILURE OF DRIVE
Failure of the drive is evaluated on the basis of signal from frequency inverter.
CAUSE:
1. Failure message of frequency inverter
10
Wait until the machine cools down, or cool it down
by ironing of wet linen (use some old linen as it
can be damaged by the high temperature)
Professional servicing is necessary
Change temperature sensor, check the
connection of the sensor
Press the button again for starting the reverse
operation or press „Start" again to start the normal
operation.
Start the normal operation by the button „Start".
When it is not possible, check, whether the crank
is not jammed in the insertion position, or the micro
switch got jammed on the crank (inside the stand).
Start the normal operation by the button „Start".
Switch the machine OFF and ON again. If it's not
possible to start it even now, cool it down by wet
linen and rotating the handle. After cooling the
machine down below 80°C, repair the drive.
Check ventilator(s).
Check and clean exhaust pipeline.
Try to switch the machine OFF and ON again, or
let the inverter cool down. If it doesn't help, look
for error according to individual instruction for
inverter.
