NOTE: The programming plug positions referred to in the calibration
procedures are upper/lower or left/right as viewed on the installed analog
board. This refers to the plug position when inserted on two pins of a
3-pin group. The IN or OUT position referred to in the procedure refers
to a 2-pin group where the plug is either fully inserted or inserted on only
one of two pins, electrically floating. Refer to Figure 5.2 for the locations
of the programming plugs, potentiometers and test points.
1. Turn off power to the I/O chassis.
2. Connect the analog circuit board to the extender board and install
them in the right-hand slot (slot 1) of a module group.
3. Set the programming plug positions on the analog board for voltage
mode.
E3 (E1) V, upper position
E5 (E4) IN position
E6 V, left position
(E2) upper position
E8 (E7) V, left position
E18 upper position, standard compliance
4. Locate and jumper the pair of test pins on the digital circuit board.
Install the digital circuit board in the adjacent left-hand slot of the
same module group.
5. Connect +15V dc and +5V dc power supplies. Be sure the
programming plugs E23 and E24 are set for your source of +5V dc,
backplane or external supply. Be sure all other I/O are disconnected
from the PID module.
WARNING: All inputs and outputs (except for the +15V dc,
-15V dc, +15V dc COMMON, +5V dc and +5V dc COMMON
terminals) must be disconnected from the PID module during
calibration. If connected to the system, unexpected machine
operation could occur with possible damage to equipment
and/or injury to personnel.
6. Install a PC processor whose memory, containing a 256 word data
table, has been cleared.
