The EC 8-256 electronic control unit has been specifically designed for the control of gas or electric deep fryer. It is composed
of a power and a keyboard, which are connected by a 16-pole cable.
The unit input can be used with "J" (Iron-Constantan) or "K" (Chrome-Alumel) type thermocouples depending on factory settings.
The oil average temperature control is divided in three phases:
"pre-heat" (melting), when the unit output is energised with cyclic control until a temperature threshold is reached (this threshold can
be set by parameter configuration); this operation with reduced power at start-up avoids fast temperature increases and facilitates the
melting of fat used for frying
"conservation", when constant oil temperature is maintained; in this phase it is possible to maintain the temperature of melted oil before
frying, and to avoid the fat becoming dense again
"main control", when a P.I.D. temperature control (Proportional, Integral and Derivative) is active until the required temperature is
reached; in the last two phases an LED indication is available when the oil temperature approaches the required value, and the buzzer
gives a specific signal when such value has been reached.
The unit can be used for the control of both electric and gas deep fryer. The set of parameters that is specific for each type of deep fryer
can be easily set by a dipswitch located at the back of the keyboard.
An analogue memory, which is standard supply for this device, allows maintaining the temperature control in the event of short power
supply failures. In this case the unit will start again and revert to the same operating condition that it had before the failure.
The output is a NO relay that can drive a maximum of 6 A @ 250 Vac. All connections are made by robust 6,3 mm faston type connectors
(for the probe, the power supply and the output).
A buzzer and a flashing indicator have been included to warn to the user in the event of irregular operating conditions: probe failure,
data memory failure and temperature measurement outside the probe operating range.
The unit is also provided with a temperature alarm that can be disabled, and that can be configured is six operating modes: in the event
of alarm intervention the buzzer gives an intermittent signal while the display shows the warning label "AL1" alternated with the temperature
measurement.
