DESCRIPTION

The ACL 3000's versatility allows you to change between all three models without changing the ignition controller, eg. The continuous spark ignitor can be upgraded to a continuous pilot auto-matic re-light simply by changing the ignitor rod assembly.

Theory of Operation

The ACL 3000 utilizes a single ignitor/flame rod to provide both flame acknowledgement and ignition at the pilot tip. When the ACL 3000 starts its ignition sequence, fuel gas travels to the pilot tip where the ignitor/flame rod is located and sparking. Once the gas is lit, the flame becomes a current path for the ignitor/flame rod for flame acknowledgement and the unit stops sparking. If this flame is ever to blow out, the current path is broken and the ignitor/flame rod starts sparking within 1 second.

Setting Spark Gap

Spark gap should be approximately 1/8" and is factory preset.

Ignitor Rod Adjustment

There are three ignitor rod adjustments that can be made in order to achieve correct position¬ing of the pilot tip for reliable light off.
• Ignitor rod can be adjusted up or down on the trolley arm by loosening the 4 bolts, which hold the ignitor rod itself.
• The trolley arm can be adjusted up or down by loosening the (2) two bolts on the trolley as-sembly.
• The angle at which the ignitor rod tips into the shroud can be adjusted by changing the hole patterns on the trolley wheels.

Electrical Connection

The electrical drawing provided with each unit mounted in the control box will provide enough information for connection of the unit and troubleshooting if required. The ignitor box mounted on trolley is already connected to the cabtire. The only connections required are the power supply hook-up and the cabtire wire from the ignitor box into the control box.

Piping Connections

The ACL 3000 comes with a regulator, gauge and %" flexible hose. The 1/8" hose is to be di¬rectly connected to the output of the regulator. Gauge to be also mounted on regulator. A clean, dry fuel gas supply is to be piped to inlet of the regulator and not to exceed 150 psi. Regulator can be mounted close to the bottom of stack approximately 3 to 4 feet above the ground.

Start-Up

After electrical connections and piping connections are completed, ensure supply gas is purged of any solid particles as they may get caught in the pilot orifice. Install trolley into rail system and hoist with hand winch. The pilot line should be fed into the rail portion to protect it from the elements and wind. Once the ignitor and trolley have been hoisted, press the start button and then turn on fuel gas (5-10 psi). The unit will now be in normal operating service.

Alarm Output

Alarm output status provides the user with a normally closed and normally open set of dry contacts. The only time these contacts change state is when the controller has been unsuc-cessful in lighting the pilot assembly after 1 try.

Run Status

This output provides a run status of the controller. These contacts are a normally open set of dry contacts when the controller is off or in alarm state. When the controller is running nor¬mally, these contacts are closed.

Restart Timer

The ACL 3000 comes with a restart timer so that when the controller goes into alarm mode the restart timer (T3) is activated and will clear the alarm and begin start sequence again. The time increments are 15 seconds, 1 minute 15 seconds, 2 minutes 15 seconds, and so on.

Re-Setting the Controller

Re-setting of the controller is required when:
• Power outage occurs
• Stop button is pushed inadvertently
• Pilot gas is lit from a source other than the ignition module.
To reset, the operator must turn off the fuel gas and press the stop button of the controller. Wait 1 minute, then press the start button ,then turn on fuel gas while in ignition mode.

ADDITIONAL INFORMATION

Note 1: Restart cycle is continuous until pilot flame is established and acknowledged.
