Program Lockout Switch
When the PROGRAM LOCKOUT switch is set to position 2, all
programmable meter functions can be changed.
When set to the ON position, the PROGRAM LOCKOUT switch
prevents any programming changes being made to the meter. If
programming is attempted, the meter displays [LOC]. The ON
position allows programming parameters to be viewed but not
changed.
See Display PCB without Faceplate and Bezel diagram.
Setpoint Lockout Switch
When the SETPOINT LOCKOUT switch is set to position 1, the
setpoints can be programmed. Once the setpoint values have
been entered and the SETPOINT LOCKOUT switch set to the
ON position, the setpoints can be viewed but not changed.
See Display PCB without Faceplate and Bezel diagram.

Test Pin
Configure Code 9 to [0XX]. When the TEST pin (pin 11) is
connected briefly to the COMMON pin (pin 11) all segments of
the display and setpoint annunciators light up. Six eights and
six decimal points (8.8.8.8.8.8.) are displayed for a short peri-
od. The microprocessor is also reset during this time, losing all
RAM settings such as peak and valley, and any digital input pin
settings set up in Code 9.
The TEST pin can also be configured in Code 9 to carry out the
following (see
Front Panel Programming Codes
on Page 9):
• Reset counter channel 1 and total 2 at power-up [1XX].
• Reset counters, CH1, CH2, CH3, CH4,- total 1, and total 2 at
power-up [2XX].
• Reset total 1 and total 2 at power-up [3XX].
Capture Pin
When the CAPTURE pin (pin 12) is connected to the COMMON
pin (pin 11), the CAPTURE pin can be programmed for setpoint/
relay activation or macro control applications in the setpoint control
settings mode of the setpoint programming mode [SPC-X] [X2X] .
Common Pin
To activate the LOCK, HOLD, TEST and CAPTURE pins from the
rear of the meter, the respective pins have to be connected to the
COMMON pin (pin 11).
The LOCK pin can also be configured in Code 9 to carry out the fol-
lowing functions (see
Front Panel Programming Codes
on Page 9):
• Reset channel 1 [XX1].
• Reset channel 2 [XX2].
• Reset channel 3 [XX3].
• Reset channel 4 [XX4].
• Reset tare [XX5].
• Reset total 1 [XX6].
• Unlatch (de-energize) all setpoints [XX7].
Hold Pin
Configure Code 9 to [X0X]. When the HOLD pin (pin 9) is
connected to the COMMON pin (11) the displayed reading is fro-
zen. However, A/D conversions and all control functions continue
and as soon as pin 9 is disconnected from pin 11 by the switch, the
updated reading is instantly displayed.
The HOLD pin can also be configured in Code 9 to carry out the fol-
lowing functions (see
Front Panel Programming Codes
on Page 9):
• Reset channel 1 [X1X].
• Reset total 1 and total 2 [X2X].
• Reset total 2 [X3X].
• Reset peak and valley [X4X].
• Reset tare [X5X].
• Set tare [X6X].
• Unlatch (de-energize) all setpoints [X7X].
The main programming mode can be entered, but only the bright-
ness setting adjusted. After adjusting the brightness setting, press-
ing the
P
button displays [LoCK].
Lock Pin
By configuring Code 9 to
[XX0], connecting the LOCK
pin (pin 8 on the main PCB)
to the COMMON pin (pin 11
on the main PCB), locks out
the main and setpoint pro-
gramming modes. All meter
programming codes and
setpoints can be viewed but
not changed.
Error messages usually
occur during calibration pro-
cedures. The three most like-
ly causes of an error mes-
sage are:
1) The full scale and zero
signals were too similar.
Note, the high input (full
scale) signal must be at
least 1000 counts greater
than the low input (zero) signal (positive and negative values
are allowed).
2) The scaling requirement exceeded the capability of the meter
(–199999 to +999999).
3) No input signal present, or incorrect connections.
