DIP Switch Locations and Functions
The Watlow Series 998 has at least one and as many as six 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, to provide power for external signal conditioners 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.
