PANEL INTERIOR COMPONENTS

CR-1 RELAY (P/N E100-205):

Relay CR-1 is controlled by the Low Level Shutdown Device contacts C - B (NO) (normally open). Relay CR-1 contacts 8 – 7 (N.C.)

(normally closed) control the 120V power to the LOW LEVEL FAULT light. CR-1 relay contacts 6 – 8 (N.O.) control the 120V power to

the BURNER switch.

CR-2 RELAY (P/N E100-205):

Relay CR-2 is controlled by the normally open (NO) contacts 14 – 15 of the FUJI Temperature Control. Relay CR-2 contacts 6 – 8 (N.O.)

are connected in parallel to the 3T & T connections on the Burner Control. Opening and closing relay contacts 6 – 8 will initiate or

terminate the heating cycle.

CR-3 RELAY (P/N E100-382):

Relay CR-3 is controlled by the internal alarm contacts of the burner control (diesel burner) or by Relay CR-5 contacts COM and NO (LP/

NG burner). The Relay CR-3 controls 120V power to the Accessories Power Receptacle via contacts COM and NC. The BURNER FAULT

light is controlled by Relay CR-3 contacts COM and NO. 120V power to the Relay CR-3 COM is controlled by Relay CR-1 contacts 6 –8

via the BURNER switch.

CR-4 RELAY (P/N E100-359):

Relay CR-4 Operating Coil is energized (powered) by the PUMP switch. Relay CR-4contacts 2 – 3 (N.O.) control the 120V power to the

HTF Pump.

CR-5 RELAY (P/N E100-383): (LP/NG burner only)

Relay CR-5 is controlled by the burner control’s alarm contacts..

Relay CR-5 contacts COM – N.O. close during a burner fault to power the Relay CR-3 12 volt DC coil. Relay CR-5 is located beneath

the

Burner Control.

T-1 TRANSFORMER (P/N E100-220):

Reduces 120 volts AC

current to approximately 12.6 volts AC current.

RECTIFIER (P/N E100-225):

Converts 12.6 volts AC

current to 12.6 volts DC current as an operator safety feature of the rewind circuit.

FUSE 1 TYPE FNM-3 (P/N E100-356):

Provides circuit protection for the Rewind Motor and the line voltage portion of the Rewind Circuit.

FUSE 2 TYPE 3AG, 5.0 SB (P/N E100-357):

Provides circuit protection for the low voltage portion of the Rewind Circuit.

TERMINAL STRIP:

A transitional connection point between control panel interior and exterior components.

Numbered connection points share the same number as the wire connected to them.
