Heaters / Calentadores
This display shows the temperatures in the isocyanate (ISO) and polyol (RESIN) heaters. To
enter new temperature settings, press the MODE button
,
select the desired temperature by
pressing the UP/DOWN
buttons and press the MODE button again to confirm the selected
value.
The lower pushbuttons switch the heater of each product on and off. Each pushbutton
incorporates an LED which lights up when the heater is operating; a flashing LED indicates that
the heater is on but is not heating up.
The heater will temporarily stop working in the event of excess pressure in either of the heating
circuits, and will switch on again once the problem has disappeared.
If the temperature control sensor is not active, the symbol
(---)
will appear on the display and the
heater will switch off.
The hose heating command is not memorized by the unit and therefore it must be activated on
every power-up.

Mode button
Press this button to modify the different control parameters.
5.
Up / Down buttons
Increase or decrease the value of each parameter.
6.
Counter / Contador
This display indicates the number of cycles completed, and the number of cycles remaining.
The cycle counter is incremental and can be reset to zero by pressing the UP and DOWN
buttons simultaneously.
The system offers a certain number of work cycle pre-selects. When the unit completes the pre-
selected number of cycles, it stops dispensing product.
To enter the desired number of cycles, press and hold the MODE button until the cycle counter
starts flashing, then select the number of cycles by pressing the UP / DOWN
buttons as
required. Then press the MODE button again to confirm the number of cycles.
When the unit starts, the number of completed cycles is deducted from the number of pre-set
cycles. When all the pre-set cycles have completed, the counter displays zero and the unit
stops.
The counter display alternately shows (at intervals of two or three seconds) the number of
cycles completed (totalizer) and cycles remaining (preselector). The remaining cycles are
displayed with a minus sign (-) in front (-XXXXX).
The cycle counter display also shows alerts in the event of malfunction.
You can use the programmable counter cycles as minimum product level in the tanks, setting
the counter to 620 cycles and ensuring that the tanks are full. When the counter reaches zero
the machine stops in order not to pump air into the system and alerting the lack of product in the
tanks. Once the 620 cycles you should reset the counter and fill the tank if you want to reuse as
a low level of product tanks.

Control / Power button
This button controls the power switch providing electrical power to the heating circuits of the
heaters and hoses. When pressed, this button lights up. To disconnect the power supply, press
this button again. The power supply automatically cuts out in the event of an alarm for excess
temperature in the heaters (alarms 6 and 7) or an alarm for excess intensity in the hose heating
(alarm 9).
