The following information will first describe the sprinkler circuit components and then provide a circuit
description. Please refer to the ADS-464 ladder diagram (which is supplied with the machine) as the following
is described.

SPRINKLER CIRCUIT COMPONENTS

• OL12 (overload #12) is a 1.6-amp magnetic and thermal overload device set 1-amp. Its function is to protect

and the line voltage of the sprinkler circuit.

• T1 is a control transformer whose primary depends on the system line voltage (i.e., 208 VAC, 240 VAC,

380 VAC, 416 VAC, and 480 VAC). Refer to system’s nameplate. Its secondary is 110 volts AC.

• L3 is a “

RED

” indicator installed on the electrical enclosure door. Its function is to indicate the presence of

110 VAC to the sprinkler system.

• Sprinkler High Limit Controller (SHLC) - Its function is to monitor a preset hi-limit temperature (which is

currently set to 550º F [287.8º C]) and to control the activation of
the “WATER SPRINKLER” circuit.

• SHLC’s (Sprinkler High Limit Controller’s) temperature information is derived from the RTD #4

(Resistive

Temperature Device #4)

, a resistive sensor located on the top right hand side of the tumbler (basket) section.

Its exact location is in proximity of the intake and hi-limit temperature probe.

IMPORTANT

: An open RTD (Resistive Temperature Device) probe or disconnecting the probe under

power will cause the sprinkler to active.

•

ALL

ADS-464 RTD

(Resistive Temperature Device)

probes are rated for 1,100º F (593.3º C).

• SHCL #2 (Sprinkler High Limit Controller #2) contacts (alarm and set point) are configured in the normally

open state.

• #2CR (#2 control relay) and #3CR (#3 control relay) are relay coils that are energized in a logical manner for

circuit control. The following are their associated relay contacts information.

• S11 and S12 are the actual electrical solenoid connections that turn on or shut off the air actuated water

valve. The electrical connections for S11 and S12 are located in the solenoid junction box in the burner
section of the ADS-464

• S11 = Sprinkler ON
• S12 = Sprinkler OFF

IMPORTANT

: For proper sprinkler and dryer operation, sprinkler

must be

or dedicated” single-phase (1ø) multi-wire branch circuit at dryer’s nameplate voltage.
