RCB 200 - STRICTLY DESIGNED AS PER

ES-XW7T-1A278-AC

The circuitry of the RCB 200 is strictly following the

requirements as per Ford given in Annex G, Figs. G-1 and

G-2 for transient pulses A1, A2, B1, B2 and C, using the

components specified by Ford.

The two test modes are achieved based on the relay

circuit details given in Figs. G-3 and G-4 of Annex G.

MICRO-PROCESSOR CONTROLLED RCB 200 ENSURES

EASY OPERATION

With its 6 different pulses and two different modes to

sequence these test pulses the RCB 200 is easily

operated by only three function keys. A micro-controller

automatically sets the circuit required to generate the

selected pulse in the predifined mode (fixed mode with

specified repetition and duty cycle (pulses A1, A2, B1 and

B2) or random (pulse C)).

The RCB 200 can also be used for tests as per CI 260F.

Test modes 2 and 3are based on a pseudo-random timing

of the application of pulses. This is done automatically by

the built-in microprocessor. All tests can be performed in

sequence or endless.

The Potter & Brumfield relay must be replaced because of

the life and wear after 100 hours of tests. An integrated

counter actively monitors the operating time of the relay.

The EOL LED (end of life) indicates the current EOL status.
