close the relay, and an MCS-11 OFF command will open the relay. The configuration program
also allows you to make any of the outputs act in a momentary fashion. If momentary is selected,
then the relay is operated for 200 milliseconds for each MCS-11 ON command. MCS-11 OFF
commands are ignored for points selected as momentary. You may set the amount of time that a
momentary control point (status) is reported as ON using the configuration program.
ANALOG INPUTS:
An optional analog input card is available. This card provides 16 voltage-
measuring inputs that can be mapped as a set to any one of the RAS scanners. Each input can be
set to any one of the ten input ranges in
Table 1
below. MCS-11 Remote Analog Scanners (RASs)
can contain up to 24 values, and each value can range from 000 to 999. An input voltage equal to
the maximum of the range selected will cause the analog scanner value to be set to 999.
Table 1
below lists these values to the precision required. The values in the right column of the
table represent the multiplier constant to be used in configuring an MCS-11 master, such as the
NGM, TSM-8000, TSM-2500, TSM-3500, DCP-1500, etc. The MCS-11 master will multiply each
RAS value by the multiplier you set in order to convert the value to the proper range of counts (the
typical units setting is ‘voltage’). You will need to enter the proper multiplier for each analog point
into the master so that it can display the counts from the 2310 AL properly. Note that for negative
input ranges, the multiplier is a
negative
number.

Table 1. MULTIPLIERS FOR MCS-11 MASTER CONFIGURATION
The analog inputs are generally measured relative to a common ground. However, pairs of inputs
may be set to differential input mode. In differential mode, the measurement is made between the
two inputs of the pair, rather than between an input and ground. If input
1
is set to differential
mode, then input
9
automatically becomes the other input of the pair. In this case, point 1 in the
RAS will hold the differential value, but point 9 will always have a 000 value. If input
2
is set to
differential mode, then input
10
becomes the other input of the pair, and so on. The configuration
