;
R7848A
and
R7848B
(AMPLI-CHECKTM)amplifiersusedwiththeBCS7700and
7800 SERIES flame safeguard controls respectively, have a
dc voltage flame signal output.
Most existing Honeywell flame safeguard controls have a
flamecurrentjackonthecontrolplug-inflameamplifier.The
flame signal (current) can be measured
with
a volt-ohmmeter
such as the Honeywell W 136A with a zero to 25 microampdc
scale. To measure the flame current (signal), a Cable Connec-
tor (part number
1%146,
included with
W136A)
must be
used with the meter. With the
W136A

flame signal (voltage) measurements are made as shown in
Figs. 13 and 14. The positive (red) meter lead is
connected to
the

lead to the negative
