3.4: Number of Outputs
The 1995A comes programmed for six outputs, but it is expandable to 30 outputs. However, when
using a Remote Circular Display, the maximum will be 24 outputs.
3.5: Selecting Number of Outputs
Selection of the number of outputs should be done after the desired scale factor is entered, and before
any other programming is done. See Chapter 4: Expansion Modules.
A) To program the number of outputs desired, the unit must be in the Program mode, then depress
. The unit will then show the number of circuits previ-
ously stored. To change the number of outputs desired, enter the number of relays in multiples
of six and depress .
1) Valid numbers for are and
. Remember, if using a Remote Circular Display, the maximum number of
outputs is 24.
NOTE: If a number is entered that is not a multiple of six, the unit will store the next multiple of six.
3.6: Multiprogram
(Available Only on “P” Option Units)
The Multiprogram feature allows the storage of multiple sets of output sequences that are
preprogrammed based on the various requirements of different tooling. When dies or tooling are
changed, the new program is simply called up on the keypad and all outputs are automatically set to the
new output sequences. The number of available programs will vary based on the number of output
limits and the number of setpoints programmed on each limit. A typical six-limit system with one “ON”
and one “OFF” setpoint per output will be capable of storing twenty programs in memory
A setpoint is one “CIR ON” or “CIR OFF” entry. The following formula shows the relationship
between the number of output relays, the number of programs, and the number of setpoints available
per program.
