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

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.
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.
