For time/temp displays using a thermocouple (red wire on #9 and white wire on # 10),									* Off for °F
set the dip switches as follows:									* On for °C

FOR 23 SEC. TO 30 MIN. CONVEYOR TIMES

NOTE: For time/temp displays using a thermistor (2 yellow wires on terminals 9 & 10), set the dip switches as follows:

1.With conveyor running, set conveyor speed control so Time/Temp. Display indicates 5:00 minutes. Place a pan on the conveyor, measure (STOPWATCH) the time (SPEED OF PAN) of the leading edge in to leading edge out of oven. Turn the time adjustment pot. on the rear of the Time/Temp. Display so display agrees with time measured by the stop watch.

2. Turn conveyor speed control fully counterclockwise and adjust the stepper control	maximum speed pot(refer
to drawing Pg. D-19) so the display indicates 50 seconds.

3.Turn conveyor speed control fully clockwise and adjust the stepper control minimum speed pot so the display indicates 30 minutes.

NOTE: Repeat 4 and 5 to be sure settings are accurate.

4.Turn power off and set #1 dip switch to its (ON/OFF) other position and verify that the conveyor reverses direction when power is applied. Set conveyor travel direction as customer requests.

CAUTION: ALWAYS REMOVE POWER BEFORE CHANGING CONVEYOR DIRECTION.

TO REVERSE CONVEYOR DIRECTION ON STEPPER DRIVE SYSTEM

1.Shut off power at main breaker.

2.Remove conveyor.

3.Remove front control box cover.

4.Change position of dip switch #1 on stepper control board as described on Page D20

5.Reassemble in reverse order.

TRANSFORMER - STEPPER MOTOR CONTROL

1.Shut off power at main breaker.

2.Remove conveyor.

3.Remove front cover.

4.Disconnect transformer wire harness.

5.Remove two (2) mounting screws.

6.Reassemble in reverse order.
