as close as possible above the nominal full scale value within the limits specified in Table 4-3
for +FULL SCALE VPR LIMIT. Press
%
once.
6. Press
#
- NEGATIVE to adjust the maximum negative protection limit of the power supply.
Adjust as needed until the reading is as close as possible above the nominal full scale value
within the limits specified in Table 4-3 for –FULL SCALE VPR LIMIT. Press
%
three times.
7. Press
#
- EXTRL CONTROLS,
$
- EXTERN PROTECT. Connect 0V ±0.1mV d-c refer-
ence voltage from the external voltage source to the following pins of analog I/O connector
(A2A5J6) referenced to pin 12 (GND1):+V_LIM_EXT (pin 14), –V_LIM_EXT (pin 6), +I_LIM–
EXT (pin 13) and –I_LIM–EXT (pin 5). Then press
!
- ZERO. This enables the BOP to rec-
ognize that the voltage at the four _EXTERNAL pins (14, 6, 13, and 5) is 0V. Press
%
once.
NOTE: Accuracy of the 10V d-c reference must be ±0.1mV in order for the calibrated unit to
meet published specifications.
8. Press
$
- EXTRL PROTECT. Replace 0V ±0.1mV d-c reference voltage at pins 14, 6, 13,
and 5 with +10.0V ±0.1mV d-c reference voltage from the external voltage source referenced
to pin 12 (GND1) of the analog I/O connector (A2A5J6), then press
@
- MAXIMUM. This
enables the BOP to recognize that the voltage at the four _POSITIVE pins (14, 6, 13, and 5)
is 10.0V. Then press
%
twice.
9. Disconnect +10.0V d-c reference voltage from pins 14, 6, 13 and 6 of analog I/O connector
(A2A5J6). Connect a +0V ±0.1mV d-c reference voltage to EXT_REF, pin 11, referenced to
pin 10 (SGND1), of the BOP analog I/O port (A2A5J6).
10.Press
!
- VOLTAGE,
#
- EXTERNAL,
!
- ZERO to set the BOP to zero volts output.
Adjust as needed until the DVM reads as close to zero as possible within the limits specified
in Table 4-3 for VOLTAGE ZERO. Press
%
twice.
11. Press
@
- GAIN,
!
- ZERO to set the BOP to zero volts output. Adjust as needed until the
DVM reads as close to zero as possible within the limits specified in Table 4-3 for VOLTAGE
ZERO. Press
%
twice.
12.Connect +10.0V ±0.1mV d-c reference voltage from the external voltage source to
EXT_REF, pin 11, referenced to pin 10 (SGND) of Analog I/O Port connector (A2A5J6),
Press
@
- GAIN,
@
- POSITIVE. Adjust as needed until the DVM reads as close to zero as
possible within the limits specified in Table 4-3 for VOLTAGE ZERO. Press
%
twice.
13.Press
#
- EXTERNAL,
@
- POSITIVE. Adjust as needed until the DVM reads as close as
possible above the nominal full scale value within tolerance specified in Table 4-3 for +FULL
SCALE VOLTAGE. Press
%
three times.
14.Connect a 0V ±0.1mV d-c reference to pin 8 (S_IN_SERIAL) of the PAR/SER CONTROL IN
connector (A2A5J3) referenced to COM_S (use mating connector supplied with the unit, P/N
142-0488 to gain access to PAR/SER CONTROL IN connector pins). Press
#
- EXTER-
NAL CONTROLS,
@
- SERIES, and
!
- ZERO to set the BOP output to zero volts. Adjust
as needed until DVM reads within tolerance specified in Table 4-3 for VOLTAGE ZERO.
Press
%
once when done.
15.Connect a –10.0V [–6.0V for BOP 6-125MG] ±0.1mV d-c reference to pin 8 (S_IN_SERIAL)
of the PAR/SER CONTROL IN connector (A2A5J3) referenced to COM_S. Press
@
- POS-
ITIVE to set the BOP to +10.0V output [+6.0V for BOP 6-125MG]. Adjust as needed until
DVM reads as close as possible to +10V [+6V for BOP 6-125MG]. Press
%
three times
when done.
