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.
