Step 6: Hardware
A. Would the controller fit your applications panel
better in its vertical configuration (986 or 988) or
horizontal configuration (987 or 989)? Be sure to
check all dimensions for fit.
B. Will you connect your controler to a 100- 240-
volt power supply (988 or 989) or a 24-28-volt power
supply (986 or 987)? (Either configuration works
with either AC or DC power.)
C. Each of the two displays in the 988 family can be
either red (R) or green (G). Choose a color for each
display.
D. You can lockout access to controller settings with
software, hardware switches or with an digital event
input. All of these are standard features.
E. Fill in the appropriate spaces in your photocopy
of the worksheet from page 7.10. You should have
