MAINTENANCE PROCEDURES (continued)

During warm-up, both displays flash while showing the last-used MENU settings.

A MENU cycle cannot be started while in warm-up mode. However, MENU keys may be programmed during warm-up.

Program mode is disabled when either timer is counting down.

A programmed cycle cannot be started when display is flashing (warm-up mode).

Any changes to the left preset timer programs are copied right section. The right program settings can then be changed and stored. Right program settings are retained until the left section is reporgrammed, at which time left program information is again copied to the right section.

When setpoint temperature is reached, the display stops flashing and the audible alert beeps 3 times.

STANDARD OPERATION NOTES:

Standard pre-set MENU programs are as follow:

PROGRAM	TEMP	TIME	FUNCTION
1	450º	00:14
2	450º	00:27
3	450º	00:35
4	275º	00:00	CLEANING

On start-up or changing program settings, the display will flash until the new temperature setpoint is reached (i.e. heater cycles on or off). This occurs whether approaching a setpoint from above or below.

Both lower platen zones and both upper platens are controlled by the individual setpoints. Deadband is ±2º.

Press TEMP to display actual temperature of the lower platen.

PROGRAMMING TIME AND TEMPERATURE (LEFT SECTION) NOTE:

•You may program MENU keys during warm-up or during normal operation.

•Temperature settings are done with the left MENU only.

•Time settings are automatically copied from the LEFTMENU to the corresponding RIGHTMENU.

•Time settings on the RIGHTMENU may be programmed only after the LEFTMENU.

Example: Program time and temperature for LEFT MENU 1 Press and hold TEMP. While holding TEMP, press and hold LEFT MENU 1 key for 3 seconds. The LED above the MENU 1 key will glow, and the display will read “_ _ : _ _”, prompting you to enter the 4-digit access code.

Enter the 4-digit code. (NOTE: Factory setting is left MENU 1, left MENU 2, left MENU3, left MENU 4. Contact your Wells Authorized Service Agency for instructions in determining or changing your access code). Starting with the first digit, the bottom bar of the display moves to the top bar. The security code does not show on the display. Once the correct code is entered, the display changes to the preset time, and the LED for MENU 1 key flashes.
