The following jumpers are for the Model 493.25 Full-Range Digital
Universal Conditioner. The jumpers are labeled W instead of X; the W
jumpers are solder pads. The following jumper descriptions are from
the 493.XX Module Setup configuration drawing (PN 049-336-301).
Jumper W1 enables or disables an active guard for the sensor cable. A
passive guard drive is the default.
Enable
(Cap to Ground)
(Short to Ground)
Default
Jumpers W2 and W3 establish the correct shunt calibration connections
for 4-wire and 8-wire sensor cables. The length of the sensor cable
determines which type of cable is used. Short cables are typically 4-
wire cables while long cables are typically 8-wire cables.
• Jumper W2 selects a 4- or 8-wire transducer for positive feedback.
• Jumper W3 selects a 4- or 8-wire transducer for negative feedback.
• The setting of jumper W8 (single ended excitation enable) may
affect your choices for these jumpers (W2 and W3).
Note +/– excitation (–excitation is standard). See R33 or XDCR ID-W1.
Default
–EX to –FB shunt
in 4-wire config
–EX to –FBR shunt
in 8-wire config
Jumpers W5 and W7 select the local (on board) or remote (through a
cable) excitation sensor connection.
• The local selection is used with 4-wire transducer connections.
• The remote selection is used with 8-wire transducer connections.
• Jumper W7 configures the + excitation signal.
• Jumper W5 configures the – excitation signal.
Disable
-EX to +FB shunt
in 4-wire config
-EX to +FBR shunt
in 8-wire config
