At this time it is also recommended to verify that the set point upper and set point lower limits work
correctly. Lower the set value by using the down arrow until the set point reaches the lower set point limit.
Assure the set point stops at this limit. Raise the set point value using the up arrow test that the set point
stops at the upper limit. Assure the set point stops at this limit. If the above does not work correctly
review the settings in the controller as well as the wiring of the system.
Low Limit Control testing:
If the set point is adjusted above the actual process value the SUB1 LED should be ON and the system
should not run. Lower the set point using the Up arrow key and set the low limit for the application. Verify
that the SUB1 LED is still ON and that the system cannot be started. Apply a reset to the Limit controller
via event input or PF key. The SUB1 LED should go off and the system should be able to be started.

Limit controller Protection set up:
Since this is a monitoring device to protect the system from over or under temperature conditions it is
highly recommended to add a level of protection on the unit to avoid accidental changing of settings. The
unit has the ability to lock out various levels/settings by use of the protect level. Make sure the controller
is set up correctly for the application before applying protection. Below is two typical ways to set
protection on the unit. If different levels of protection are required please consult the User manual for
further explanation:
