Description
| The Simpson Motor Load Meter Relay has
been designed to provide visual monitoring of motor load current,
in addition to the control action at one or two set points. The
controller measures the AC current of a motor and indicates the
value on a 0-150% dial. The 100% point is adjusted by means of a
gain adjust potentiometer on the rear terminal block, to agree with
the 100% nominal rated load current for the motor. To prevent motor
shut down during start up or momentary transients where the motor
current exceeds the established set point, a time delay of five
seconds is provided. Delays of less than five seconds may be programmed
using external resistors. Delays up to 20 seconds are available
on special order. Specifically designed for harsh environments,
the Model 3300 series is housed in a metal case that gives complete
magnetic isolation for steel panel mounting. This commercially-sealed
meter relay is moisture and dust proof and recommended for use in
wash-down areas. The combined features of time delay, gain adjust,
and auto/manual reset provide complete relay switching for alarm,
motor shut down or other corrective action. |
