DIP Switch Locations and Functions
The Watlow Series 988LF has at least one and as many as three dual in-
line package (DIP) switches inside the controller, depending on the model
number. They allow users to configure the controller for a variety of
input sensors, or to lockout front panel access to some functions.
To set any DIP switch:
• Remove the controller from the case by pressing firmly on the two
release tabs on one side or the top of the bezel until they unsnap. Then
firmly press the two release tabs on the opposite side or the bottom of
the control until they unsnap. You will need to gently rock the bezel
back and forth to release it from the chassis.
• Use the illustrations on the following pages to locate and set each DIP
switch.
