Configuration and Test Mode
9.1
Use of Test Mode
Test mode is provided to give an easy means of testing the ILM hardware and to allow it
to be configured for specific applications. Test mode gives a menu of options arranged
in the logical order for testing, configuring and calibrating a new instrument.
9.2
Entering Test Mode
With the instrument operating normally, enter the TEST mode by holding the RAISE and
LOWER buttons depressed, whilst pressing and releasing the SILENCE button.
The message
tSt
will appear followed shortly by:
t.00
RAISE and LOWER may now be used to select a specific test in the range 1 to 11. For
example to access test 7, press RAISE seven times to display:
t.07
With the required test number displayed, press and release SILENCE. The instrument will
then enter that test, often displaying the first item in a further menu.
To leave test mode from the main test menu, select
t.00
When SILENCE is pressed, normal operation will resume. (Some tests automatically return
to normal operation on completion, without returning to the test menu.)
9.3
Test t.01 Testing the Display and Relays
Activating this test will light each segment in the display and each LED in sequence,
followed by activating each output line on the auxiliary port in turn. If relays are fitted,
they will be energised in sequence, and the internal alarm will sound unless it has been
disabled by switch S2/1. At the end of the test, the main test menu will return. (Note
that if only one channel is fitted there will be a long pause between the channel 1
display being tested and the relays being energised.) This test cycles through all the
hardware options, whether of not they are fitted.
9.4
Test t.02 Testing the Keys
When this test is activated nothing will be lit on the display until a key is pressed. For
each key pressed, one and only one, segment of a display should light. Exit from this test
by pressing RAISE, LOWER and SILENCE together.
