d) Sprinkler Digital Temperature Controller

The sprinkler digital temperature controller is a

MAN3488

 

programmable microprocessor used to monitor temperatures

 

via a Resistive Temperature Device (RTD).

 

 

 

NOTE: Operating parameters are preset at the factory and should not

 

require any adjustment.

 

 

 

2. Sprinkler System Operation

NOTE: Refer to the ladder diagram provided with the dryer for relay logic.

Master Relay -The coil in this relay must be energized in order to close the contacts needed to supply power to the dryers control system.

Relay 1 - The coil in this relay energizes if the set- point is reached closing Contact 1 and Contact 2. Contact 1 latches Relay 1 on. Contact 2 closes, turning on the sprinkler, the horn, and the reset button light. Relay 1 will remain energized until the reset button is pushed.

Relay 2 - The coil in this relay energizes if the set- point is reached closing Contact 3, de-energizing the Master Relay, and shutting power off to the dryer. Relay 2 will remain energized until the reset button is pushed.

NOTE: The Sprinkler System will remain on until the tumbler (basket) temperature falls below the set-point, and the reset button is manually activated.
