SOLUTIONS
1.
Hoses without product or air pockets in hoses
Purge the air from the hoses.
2.
The ISO heater is not delivering the required temperature
See the section on heater problems.
3.
Hose connector
Check the hose connector
’s electrical connection on the left hand side of the console.
4.
Heating element disconnected
Check that the resistance reading in the hose is 33Ω ± 2Ω
5.
F4 automatic switch
Protects against current spikes in the hose circuit. This switch is located inside the control
panel. Check that it is set to the ON position. If the switch is not working properly, replace it with
one of equal amperage.
WARNING!
Replacing the automatic switch with another of different characteristics can
damage the unit and endanger the safety of the operator.
6.
Triac
If the other checks have not revealed any problems, check the triac. Replace the triac if it is not
working properly.
7.
TCS temperature control sensor
Temperature sensor malfunctions are automatically displayed on the control panel. To
determine whether the fault is caused by the sensor itself or by a defective electrical connection,
perform the following check: unscrew the temperature control sensor’s electrical connector from
the end of the hose, and without removing any other co
nnection connect it directly to the unit’s
electrical outlet. If the control function reappears, check the electrical connections of the
temperature control sensors at both ends of the hose, and if necessary replace the temperature
control sensors.
8.
Adjusting the hose heating temperature
The purpose of the hose heating system is to keep the temperature of the products in the hose
at the same temperature as they left the heaters. Therefore, the maximum hose temperature
setting (80ºC) is the same as the maximum setting on the heaters display.
