ENERGY SAVING Function:
The equipment can be set on ENERGY SAVING to obtain important energy
savings in five different ways, by selecting the temperatures of all the channels at a
programmed % of their operating value (50% to 80%). This function disables the pump
and the external permission associated and switches on the LED and the display shows
a vertical line.
This function can be entered in five different ways:
•
By pressing the key.
•
By programming the timer.
•
By enabling the external ENERGY SAVING signal (Option)
•
By the end of a programmed time in which there has been no blue shot (Option)
•
By RS-485 communications (Modbus). (Option)
Temperature regulation:
This function enables the heating when the temperature descends 2ºC below
reference temperature and disables the heating when the temperature is the reference
temperature.
This control guarantee a longer durability of the control components and minimize the
disturbances emitted to the outside, fulfilling the EMC norm.
Pump and ready unit control:
The pressure pump and the associated external clearance relay (with power-free
contacts) are switched on when the temperature of all the resistances (tank, hoses and
guns) reaches the temperature range defined by their reference temperature and their
maximums deviations. The pump and the ready unit are switched off when any one of
them go out of the temperature range.
There is a delayed clearance parameter (P3) that provides extra heating time.
The P3 time starts when the last element reaches the temperature range. While the
temperature of the tank is in the temperature range, the delay time is inhibited.
In the heating, while the equipment is in a temperature and the delay time is not finished,
the Green LED is flashing.
Preheat Function:
The preheat system does that all peripherals (hoses and guns) are warmed up by
sequential form while the tank does it at normal speed. When the tank reaches the 75%
of the programmed temperature, the energy is applied to hoses. When the hoses reach
75% of the programmed temperature, the energy is applied to the guns.
