Diagnostics - Self Test Mode
An internal diagnostic tool can be enabled on the communication module (node) using the graphic display.
This tool allows the user to confirm that all of the inputs and outputs on the manifold and any of the distributed
modules are fully functional without needing a network connection or controller. There are two test modes that
the user can choose. The “
CYCLE OUTPUTS
” test mode tests all the outputs by sequentially turning them ON
and OFF for approximately .5 seconds. The “
INPUTS
” test mode tests the inputs by causing all of the outputs
to toggle between even and odd values when any input is made. The Self Test mode on the communication
module (node) is a global setting and will test all devices connected on the main manifold as well as any
distributed modules and/or manifolds.
Similar “local” self tests are available on all output modules types. This “local” self test function allows any
output module to be tested without affecting any other output module.
NOTE: The number of Valve outputs that are tested are affected by the I/O size settings.
To use the Self Test Mode, the user must first set some initial conditions. Follow these steps to initiate the self-
test mode.
1)
Disconnect Air and Communication from the manifold!
2)
Select the desired test mode using the graphic display. (See example below)
3)
Starting at the Home Screen, navigate the menus by selecting the NEXT button until the
DIAGNOSTICS
menu is shown.
4)
Select the SET button to access the
DIAGNOSTICS
menu and then again to access the
SELF-TEST
menu
5)
Push NEXT to navigate to the desired test mode:
CYCLE OUTPUTS or INPUTS
6)
Push SET to select the desired test mode.
7)
A message will appear:
DISCONNECT AIR HOLD SET BUTTON
8)
Hold the SET button down for approximately 10 seconds to enable the test. The Display will flash
the above message while the button is pushed.
9)
When the display stops flashing, the self-test mode will run and the Module Status LED will flash
Red/Green while the display shows
SELF TEST RUNNING.
10)
The global self-test mode can only be disabled by disconnecting the power to the manifold.
