C24GA SERIES CONVECTION STEAMERS - SERVICE PROCEDURES AND ADJUSTMENTS

AUTOMATIC IGNITION SYSTEMS

When the main power switch is turned on and the water level is above LLCO, the ignition control module is energized with 24 volts between terminals five and six. High voltage is sent from terminal nine to the spark electrode and an output of 24 volts is sent from terminals two and three to the pilot coil in the combi- nation valve, allowing gas to flow to the pilot. The sparking will continue for 90 seconds or until the flame sensor has confirmed that an adequate pilot flame is present.

Once the pilot flame is confirmed, a 24 volt output from terminal one will be sent to the gas combination control valve.

TERMINAL

DESCRIPTION

NO.

1

Voltage (24 VAC) will be present on MV

 

terminal #1 with the pilot sensing

 

electrode sensing an adequate pilot

 

flame. This output will remain present

 

as long as the pilot flame remains

 

adequate.

2

Common MV/PV.

3

The Pilot Voltage (24 VAC) will be

 

present on terminal #3 at the instant

 

an input voltage is supplied to the

 

module. This voltage will remain

 

present on terminal #3 providing an

 

adequate pilot flame is established

 

within 90 seconds. In the event that an

 

adequate pilot flame is not established

 

within 90 seconds this output voltage

 

will drop out.

4

Ground (burner).

5

Ground (24 VAC Neutral).

6

24 VAC Input.

8

Flame Sensor.

9

High Voltage to spark electrode.

 

 

Spark Ignition Control Test

The ignition control module and ignition control module transformer are located in the electronics enclosure behind the generator base front cover.

1.Check for earth ground.

2.Check to ensure that all electrical terminal connections on the ignition control module and the igniter are clean and tight.

3.Verify that the ignition control module and the igniter have good ground wire connections. The igniter mounting bracket should have good metal to metal contact to its mounting surface.

4.Turn the main power switch on. Make sure LLCO light is on.

5.Check for 24VAC output on the ignition control module transformer.
