INDICATION

There are two LED’s on the front of the D64RPB100.

Green RUN LED

Flashing: Okay

Off:

No control voltage or D64RPB100 defective

Steady on: Control voltage too low or D64RPB100 defective

Red TRIP LED

Off:

No trip

Steady on: Trip

2.5

RESET

The D64RPB100 has a built in momentary RESET button and two terminals, R1 & R2, for a

remote N.O. TEST/RESET button. After a trip, the electronics remain in the tripped state until the

ground fault has been cleared and the RESET button has been pressed, or the control voltage is

removed from terminals 1 & 2.

It is

NOT

necessary to press the RESET button after the ground fault has been cleared when the

D64RPB100 is set in the Pulsed Auto Reset mode. In this mode the relay will reset in 3 seconds.

2.6

GROUND FAULT TEST

Double clicking the RESET button on the front of the relay or double clicking the remote

TEST/RESET button connected to terminals R1 & R2 invokes a relay test. A simulated current

equal to the trip current set on the Trip Level DIPswitches replaces the measured current. After

the trip delay time set on the Trip Delay DIPswitches has elapsed, the unit should trip. This

procedure tests the functionality of the unit. Up to the time of trip the test can be cancelled by

pressing RESET. The trip current and, therefore, the set point can be read at the D64D1 display, if

connected to the D64RPB100.

A “Test Record Form” is included in this instruction manual. This form provides spaces to record

the date the test was performed and the results. Those in charge of the building’s electrical

installation should retain the form in order to be available to the authority having jurisdiction.

INSTALLATION INSTRUCTIONS

Place the D64RPB100 in a clean dry enclosure. Try to keep the exposure to mechanical shock

and vibration to a minimum, even though the internal electronics have been encapsulated in

epoxy to improve the performance in high vibration environments.

Locate the relay close to the isolating device (circuit breaker or contactor) that is protecting the

circuit being monitored. If using an external or interposing CT keep the distance between the relay

& CT as short as possible.

Provide maximum clearance between the D64RPB100 (and the external or interposing CT if

being used) and any strong magnetic flux producing devices such as power transformers,

autotransformers, control transformers, reactors, and high power conductors and buswork.

CAUTION: For reliable ground fault detection by the D64RPB100 use one CT configuration only:

Built-in CT; External CT; or, Interposing CT. (i.e. do not pass power conductors through

the built-in CT when using an external CT or an interposing CT.)

3.1

MOUNTING

Refer to Figure 4 for mounting dimensions of the D64RPB100 relay. It is designed to be mounted

with either mounting screws or 35 mm DIN rail.

Two #8-32 x 3/4" (M4 x 20) mounting screws are required for screw mounting.

For DIN rail mounting the rail should be bolted to a flat surface. Install the DIN rail horizontally.

Allow at least ¾” (20 mm) of rail to extend beyond each end of the relay.
