Manual Override Module XFR522A for XFL522B (Analog Output)
The XFR522A manual override module mounts directly on
top of the XFL522B. Eight potentiometers on top of the
module can be used to independently vary the output of each
channel from 0 to 100%. Each potentiometer also has an
automatic setting which causes the channel to operate
normally. The LEDs of the XFL522B are also visible.
Manual Override Module XFR524A for XFL524 (Digital Output)
The XFR524A manual override module mounts directly on
top of the XFL524B. Six switches on top of the module can
be used to independently switch each of the digital outputs
OFF (0) or ON (1). Each switch also has an automatic setting
which causes the channel to operate normally. The LEDs of
the XFL524B are also visible.
L W Connector Module XSL511
ON ORKS
The XSL511 L W connector module provides ter-

minals for connecting to the L
terminals for the 24 Vac supply voltage for the other
EN0B-0090
W bus wiring, as well as
