The sequence for entering commands is as follows:
•
First we set the temperature of the ISO and POL heaters.
•
Next, we set the temperature of the ISO hoses.
•
Then we set the hose current consumption in amps.
•
Finally, we enter the cycle preselector setting.
If the temperature control sensor is not active, the symbol
(---)
appears on the display and the heating switches off.
The standard unit incorporate an integrated transformer. The
temperature of the hoses is controlled directly with the
corresponding keyboard on the front panel (if it has TCS) or
by programming the current intensity (see point 2 on page
14).
Select the temperature or intensity using the UP arrow button
to increase or DOWN arrow button to decrease amps and
temperature. Adjustment intensity ranges from 0 to 50 amps,
and temperature range up to 80ºC or 176ºF.
Take the values below as an approximate reference to select
the intensity that allows reaching the requested application
temperature.
30 A
38º C 100º F
35 A
48º C 118º F
40 A
60º C 140º F
45 A
75º C 167º F
50 A
80º C 176º F
NOTE:
The circuit breaker software of the
transformer has a safety system to prevent
the hoses from being exposed to high
temperatures during long periods of time.
If you have selected a potential over 35 amperes, after 20 minutes, the potential will
automatically regulate to 35 amperes.
This potential cannot be set above 35 amperes until the heater is disconnected from the
hoses and reconnected.
The setpoint programmed by the machine operator will be memorized for the next
heating start-up.
In optional versions the hoses transformer can be
independent. In this case, the temperature of the hoses is
controlled by acting on a potentiometer integrated in the front
of the transformer.
The lower pushbutton on the transformer switches the hose
heating on and off. This pushbutton incorporates an LED
which lights up when the heating is operating; a flashing LED
indicates that the heater is on but is not heating up.
Turn the potentiometer clockwise to increase amps, and anti-
clockwise if you wish to decrease amps. Adjustment ranges
from 0 to 50 amps. Turn the potentiometer clockwise until
the screen shows the required amps for a quick pre-heating.
