CURRENT
The output relay is energized when the current (peak current on AC) over-
shoots the level selected on the potentiometer. It de-energizes when the
current falls below the normal current by 5 to 50% or when input power
breaks. The hysteresis is controlled by a top mounted potentiometer and
its selection does not change the chosen current level.
The output relay is energized when the current reaches the selected value
and stays latched. The contact between terminal B1 and B2 (or 11 and 9)
should be opened or input power to the device interrupted to reset. In this
case, it is preferable to reduce the hysteresis 5%.

Note: Upon energization of the current control IR.T Series Relay,
the time delay, which is adjustable from .1 to 10 seconds, inhibits
the output relay during start-up periods. The delay time is adjustable
via a potentiometer located on the side of the case. Applies to both
versions, with and without latching.
