The displayed code may be incremented/decremented using the UP/ DOWN keys as
required. The maximum setting available is 4777. For example, the code for a
thermocouple input, DC 4-20 mA Output 1 and relay Output 3 would be 2701. When
the code is first altered, the code display will flash, until the desired value is displayed
and confirmed by pressing the Auto/Manual key.
While the Hardware Definition Code is displayed, depressing the SCROLL
key will cause the display to change to:
none or r485 or duAL
OPtn OPtn OPtn
Where none indicates the absence of any option, r485 indicates the presence of the
communications option, and duAL indicates the presence of the dual setpoint option. If
selected, the plug-in digital input board used for selection of setpoint must be installed.
NOTE: The RS485 Serial Communications option and the plug-in Dual
Setpoint option are mutually exclusive.
Another depression of the SCROLL key will cause the appearance of the
Second Input Usage menu display, which may be one of the following:
none or rSP1 or rSP3
2inP 2inP 2inP
OR
rSP4 rSP9 duAL
2inP or 2inP or 2inP
Where nonE indicates Second Input not used, rSP1 indicates the use of the Second
Input as a linear DC mV Remote Setpoint, rSP3 indicates the use of the second input
as a linear DC mA Remote Setpoint, rSP4 indicates the use of the Second Input as
linear DC Volt Remote Setpoint, rSP9 indicates the use of the Second Input as
Potentiometer (up to 2K ohm) type Remote Setpoint, and duAL indicates Dual Setpoint
switching capabilities.
Selection of Dual Setpoint switching allows the digital input part of the Remote Setpoint
option to be used for dual setpoint switching, thus permitting the instrument to have
Dual Setpoint operation and RS485 Serial Communications (the normal setpoint
switching input and the RS485 Communications option are mutually exclusive.
