COMPONENT DESCRIPTION

ON OFF

1 X Same as starting conditions

12 X Same as starting conditions

13 X Power to delime 1 (TDR)

Relay timed out, no output to delime circuit. LED

remains lit as in Turning Steamer Off.

14 X Delime Relay (K4) energized. Delime 2 (TDR) powered thru K4-6/4 closed contacts

(N.O.). 120VAC output from delime 2 (TDR) load

terminal for 60 minutes.

Power to heating circuit, power light (3LT) and WLC

thru K4-5/3 closed contacts (N.O.).

15 X Delime Relay (K2) energized. K2-6/4 contacts close (powers delime light)

K2-5/1 contacts open. Power to cooking

compartment controls is locked out (no power to

timers or lights).

Power to delime 1 (TDR) input trigger and delime 1

(TDR) is energized. 120VAC output from load

terminal remains on for 3 additional minutes after

power is removed from input trigger to allow heat

exchanger to drain (delime valve energized). Total

time 63 minutes unless canceled (delime 2 TDR

default time of 60 minutes plus delime 1 TDR of 3

minutes).

Delime transformer (3T) powered. Delime valve

energized and opens.

Delime valve end switch contacts close.

17 X Delime Relay (K7) energized. K7 powered from delime 1 (TDR) output from load

terminal.

K7-5/1 N.C contacts open. X1 potential removed

from power switch (1S).

K7-5/3 N.O. contacts close. Allows delime 1 (TDR) to

remain powered to hold K7 energized for a delay on

drop out (120VAC output from load terminal remains

on) after K4-6/2 N.C. contacts open.

All other LED's are off.
