Reduces wear on the matchless ignition.
Computer is exposed to less noise .
Pilot remains on.
Quick burner response.
Less chance of lock out.
Computer,Digital & Manual S/state controls have same plug/pin configuration.
One wiring diagram for all.

3. Gas Supply to fryer
Burner pressure - Check at either test nipple. (LP/G31-25mbar, Nat/G mbar)
Supply Pressure - Check at lower test nipple on gas valve (LP/G mbar, Nat/G20, 15-24mbar)
Manual shut off valve on each fryer
Valve is “plated” at 1/2psi max = 13.5”WC= 33.5mbar
Querying with Pitco.

4. Electrical supply to fryer
Entrance Box
Accepts 115VAC or 230VAC, selected by “locked” slide switch, into IEC320 plug.
Outputs:
24VAC for controls,
Line volts via IEC320 socket to link to next fryer,
Line volts via 3pin Molex for Opt’l Basket Lifts,
Also passes 24VDC”thru” for Basket Lift Control
120 or 208 or 230VAC is plugged into the entrance box. The switch is set to the supplied voltage. The transformer steps the voltage down to 24VAC. The temperature control will output 24VDC to Heat demand & Side on relays when required. This fryer does not use mill. Volts
Transformer - PP10429

5. “Matchless” Ignition Pilot
Spark gap 7/64¨1/64”
Spark probe also acts as Flame sensor probe.
Pilot lights when K3 “Side On” Relay is energised & stays lit if correctly sensed.
Heat Demand then energises Main coil of gas valve
The igniter will spark for 90 seconds and lock out if flame is not established.If the pilot is burning for 45 seconds or more and a lock out occurs the igniter will try one more time.
SG AllOpts

6. Pilot lights the Main burners
On the all option fryer the pilot is lit by spark igniter. The pilot remains lit all day waiting at the ready for a call for heat. When a call comes voltage is supplied to the gas valve. Gas is then supplied to the burners which is lit by the pilot.
SG AllOpts

7. Control Circuit 1 1. External Power Switch energizes transformer.
2. Voltage is stepped down to 24VAC & current flows though fuse F1 (2 Amp Slo-Blow).
Voltage and current are traced though the fryer using the verbiage and block diagram in conjunction with the colors. For pin numbers and wire colors the actual wiring diagram is needed.
SG AllOpts

8. Control Circuit 2 3. Current branches from F1:
A. Power led is energized
B. Power flows thru’ the drain switch to both DVI pins if drain switch is closed.
The DVI switch is a magnetic switch mounted on the drain valve. This switch is impervious to oil. It can have up to .4” between the sensor and actuator but it must be in alignment.
SG AllOpts

9. Control Circuit 3 3. Current also branches from F1:
C. Power flows to the back up thermostat 24VACH pin.
D. If the control transfer switch is set to MAIN power flows to the main temp. control.
The back up thermostat is an option for Computer fryers

10. Control Circuit 4 3. Current also branches from F1:
Power flows to the common contact of K3 “Side On” Relay on the relay board

13. Control Circuit 6 Ignition board Maintains the pilot
Outputs 24VAC from MV pin which feeds the common contact on K1 Heat demand relay.
Robertshaw module has LED which flashes if fault - fault code not yet known!
SG AllOpts

14. Control Circuit 7
If actual temp is below setpoint, Temp.Control outputs 24VDC to energize K1, Heat demand relay & led.
24VAC flows thru’ K1 contacts to energize the main valve.
24VAC also supplied to heat feed back pins on temp controller(s).

15. Solstice All Options Transformer
Some options may require two transformers.

16. Solstice All Options Drain Switch (DVI)
The drain switch option comes standard on fryers equipped with either a computer or a digital controller. This option helps prevent dry firing. If used with a computer the display will say draining when the drain valve is opened and say turn off after valve is closed. The fryer will not heat once the valve has been opened & then shut until the fryer is reset by turning it off and back on.
SG AllOpts

17. Solstice All Options Temperature Controls
The different controllers are interchangeable. Therefor the service man can carry any one on his truck to get a fryer up and running until a replacement can be obtained.
Controllers have black fascia to distinguish from existing Intellifry & Solid state controls & are not interchangeable
