OPTIONAL SPRINKLER CIRCUIT COMPONENTS

AUTO “EMERGENCY STOP” (E-Stop) RELAY

This device, located in the Front Right Electrical Enclosure, supplies the main control voltage to the dryer.

The ML-410’s Sprinkler Circuit supplies or removes 120 VAC to the coil of this relay for the “EMERGENCY STOP” (E-Stop) power disconnect control.

TEMPERATURE CONTROLLER

This device is located in Front Left Electrical Enclosure and monitors the Sprinkler Circuit temperature. Its operating functions are preset at the factory and should not require any adjustment.

RTD (Resistive Temperature Device) TEMPERATURE PROBE

This device is a high temperature 100 ohm (100 W) RTD (Resistive Temperature Device) Probe and is located on the upper left side of the tumbler (basket).

PNEUMATIC VALVE

This is a Dual Pneumatic 110 VAC Control Valve and is located in the lower rear base section of the dryer. Power to turn “ON” the Pneumatic Valve is supplied from the Sprinkler Control Circuit. Power to turn “OFF” the sprinkler is supplied from a manual reset button located on the Right Front Control Door.

SPRINKLER VALVE

This valve controls the flow of the sprinkler water. It is air actuated and requires air pressure to turn “ON” or “OFF.”

NOTE THAT THERE IS A “RED” INDICATING PISTON AT THE REAR OF THIS SPRINKLER VALVE.

The piston indicates the current state of the valve; when the piston is “IN” the valve is “CLOSED,” when the piston is “OUT” the valve is “OPEN.”

ALARM HORN

This component is an audible device to indicate that the Sprinkler System has tripped and that water is flowing into the tumbler (basket). The Alarm Horn will reset when the Sprinkler System is reset.

SPRINKLER RESET BUTTON

This amber colored push button is located on the Right Hand Control Door and illuminates when the Sprinkler System is activated. Attempting to reset the Sprinkler System with this button can be tried, however, if the sprinkler circuit continues to be in the active mode the reset function will not latch.
