7.2 Set Balance / Set Sensor Voltage (Technicians only!)
Set Balance
and
Set Sensor Voltage
are used when
Input Type
is for
Bridge
sensors. They are
factory configured
and only require field adjustment if the catalytic
bead sensor is mounted remote from the OLCT 200 or if a new sensor is installed.
Other input type entries draw a line through these menus and they are inactive. OLCT
200 bridge sensors may be from 2 to 6 volts excitation voltage
at the sensor
. This
means if the sensor is mounted a long distance away the voltage at the OLCT 200 may
have to be higher to compensate for losses in field wiring. Be careful not to exceed
correct sensor volts at the
sensor’s A and R terminals.
Set Balance
allows balancing of the catalytic bead sensor and must only be performed
with ZERO gas on the sensor (Figure 7-2). Balance is similar to a very coarse ZERO
calibration and does not need to be precise since subsequent calibrations will correct
for small errors. ZERO gas applied to the sensor should provide a Reading of
–3 to +3
on the SENSOR BALANCE menu.
