8.1.2 Setting the Output Hold Function When an Error
Occurs
The output hold function when an error occurs can be set to “enabled” or “disabled.” When the
function is set to “enabled,” the analog output is held at the last measured value or held at a
preset value; when set to “disabled,” the instrument outputs measured values when an error
occurs.
(1) Switch to MAINT mode and enter the password.
(2) Change the Function Number to “43.”
(3) Set the output hold function when an error occurs using the SHIFT and INCR keys. To
enable the function and hold the analog output at the last measured value, set to “1,” to
enable the function and hold the analog output at a preset value, set to “3,” or to disable the
function, set to “2.” Press the EXEC key to accept.
(4) To set a preset value, change the Function Number to “44.”
(5) Set the desired preset value using the SHIFT, INCR and DP keys. Press the EXEC key to
accept.
A preset value should be represented as a percentage of the output, i.e., 4 mA = 0% and 20 mA
= 100%. When setting a preset value to 4 mA, enter “0,” and to 20 mA, enter “100.” The setting
range is from –10% (2.4 mA) to 110% (21.6 mA). The minus sign will appear in the leftmost digit
by pressing the INCR key repeatedly to increase the blinking number: “0,” “1,” “2,” … “9,” “–,” and
returns to “0.”
8.2 Setting the Fail Contact
The Fail contact (terminals 15 and 16) is activated when an error occurs. The contact can be
programmed to be normally energized (the contact will open when an error occurs) or normally
deenergized (the contact will close when an error occurs). The contact is open when the
instrument is not powered. For details about errors, refer to Chapter 12, Troubleshooting.
(1) Switch to MAINT mode and enter the password.
(2) Change the Function Number to “45.”
(3) Set the Fail contact state using the SHIFT and INCR keys. To set the contact to be normally
deenergized (the contact closes when an error occurs), enter “0,” and to be normally
energized (the contact opens when an error occurs), enter “1.” Press the EXEC key to
accept.
8.3 Action of the Maintenance Status Contact
The maintenance status contact (terminals 13 and 14) is closed during the following states and is
otherwise open. The contact is open when the instrument is not powered.
(1) Warm-up period
(2) Stabilization period
(3) MAINT mode
The MAINT lamp is lit while the instrument is in MAINT mode. MAINT mode starts when
pressing the EXEC key while holding the MEAS/MAINT key to enter the MAINT mode and
ends when doing the same key operations to return to MEAS mode.
(4) Semiautomatic or automatic calibration
The maintenance status contact is closed during calibration including the purge time.
