Configuration Switch - S2
Prior to start-up, the switch positions of S2 must be checked against the
listing in Table 5.D to ensure proper setting. Refer to the paragraphs
following the table for switch descriptions.
ATTENTION: Only personnel familiar with the 1391B-ES
controller and its associated machinery should plan or
implement the adjustment, calibration, start-up and subsequent
maintenance of the controller. Failure to comply may result in
personal injury and/or equipment damage.
ATTENTION: An incorrectly applied or calibrated controller
can result in component damage or a reduction in product life.
Wiring or application errors, such as, undersizing the motor,
incorrect or inadequate AC supply, or excessive ambient
temperatures may result in malfunction of the controller.
