inputs:
Dec. 2016
<3> Aux. RTD input (unused)
<4> Oil Tmp RTD input
<5> Transformer secondary (P6-14)
<6> Amp Sensor auto-detect (P10-6)
<7> unused (P10-5)
<8> Amp sensor #3 (P10-4)
<9> Amp sensor #1 (P10-2)
<A> Amp sensor #2 (P10-3)
<B> 1/2 Scale (2.5v)
<C> Neg Vref (0.0v)
<D> Pos Vref (5.0v)
The displayed value can be toggled between Volts and Bits by pressing the number 0 but-
ton.
If the displayed value has a decimal point and is followed by a "V" it is voltage (0 to 5
VDC).
If no decimal point is shown, the value is
a-to-d bits (0 - 4095).
Each interlock input has an associated indicator digit.
If the input signal is currently detected, an identifying letter is displayed. If the signal is
not detected, an underscore ("_") is displayed.
8-Hd Elec:
F & M are hardwired on. P is hardwired off.
Has "C" input for pressure solenoid auto-detect.*
8-Head Electric Fryers:
DIGITAL INPUTS ABC VHDSFPM
Normal Display: A_C VHDSF_M
8-Hd Gas:
Has "C" input for pressure solenoid auto-detect.*
FPM.PM are used for ignition system monitoring
(two sets of P&M because of dual ign modules)
8-Head Gas Fryers:
DIGITAL INPUTS ABC VHDSFPM.PM
Normal Display: A_C VHDSFPM.PM
*Note:
The "C" (pressure solenoid) input can only be read when the pressure output is turned
OFF. When the pressure output is turned ON, the "C" input normally disappears.
The "C" input on 8-Head fryers is a continuity check off the pressure solenoid output. If
a pressure solenoid is connected to the controller, the controller operates the fryer as a
Pressure Fryer; otherwise, it operates it as an Open Fryer.
