WD5051 Operation
WD5051 AC current sensing relays provide current monitoring and protection
in AC systems from 50 to 400 Hz. Nominal Sensing Current, Instantaneous
Over Current setpoint, Time Over Current setpoint, and Time Over Current
time delay are user configured. WD5051 current relays operate when the
externally adjustable trip point is reached. An external time over current time
delay control is provided with an adjustment of .5 to 20 seconds. This time
delay may be used to prevent false tripping when there are slight variations in
the sensed current. With control power applied, the Instantaneous Over
Current (IOC) contacts pick-up when the input signal exceeds the IOC trip
setpoint. Similarly, with control power applied, the Time Over Current (TOC)
contacts pick-up after the preset time delay when the Sense Current rises
above the TOC trip setpoint. The IOC contacts may also be configured to
function as an under current relay. A green LED indicates power to the relay.
Red LED lights indicate the state of the IOC and TOC trips.

Remover the cover.
Adjust the TRIP SET control fully clockwise (CW) and the TIME
DELAY control (TOC only) fully counterclockwise (CCW).
Apply the desired trip current to the relay.
Slowly adjust the TRIP SET control CCW until the relay trips.
Remove the applied current (do not change the current level). Set the
TIME DELAY (TOC only) control to the desired time delay.
