METERING THE OVER CURRENT TRIP SETTING.

Unless specified otherwise, the OVER CURRENT TRIP is

set at 175% of the controller current rating at the factory.

A reference output is available to assist in the recalibration

of this setting if this adjustment is accidentally changed.

POSITIVE 1.00 V output at terminal 18 with respect to

terminal 14 equals 100% of controller current rating.

POSITIVE 1.75 V output equals 175% of current rating.

For example; on the 3629C controller, POSITIVE 1.50

volts measured at terminal 18 with respect to terminal 14,

represents an over current trip setting of 150% of controller

current rating.

METERING THE CURRENT LIMIT SETTING.

Unless specified otherwise, the CURRENT LIMIT is set at

105% of the controller current rating at the factory.

A reference output is available to assist in the recalibration of

this setting if this adjustment is accidentally changed.

NEGATIVE 1.00 V output at terminal 17 with respect to

terminal 14 equals 100% of controller current rating.

NEGATIVE 1.05 V output will equal 105% original setting.

For example; on any 3629C controller, NEGATIVE 1.05 volts

measured at terminal 17 represents a current limit setting at

105% of the controller current rating.
