indication of this test (of the selected parameter) followed by the error. An
"A" indication in the parameter section of the error code (not a selectable
parameter value) indicates the error occurred during lamp power-up before
it managed to power-up. Operation of this test is divided into four parts:
•
Upon entry, three filters, dimming iris, and diffuser open. IPRESENT
and HOT are checked. "F" appears on the display.
•
LAMP-ON is applied and the four status lines monitored.
•
Full intensity is applied and after approximately 4 sec. START is set.
Once a constant IPRESENT level is sensed (lamp on) there is an 8 sec.
warm up interval for the lamp. Within this period, intensity cannot be
altered, but the lamp may be doused (parameter = 0). Also, the state of
IPRESENT is represented on the display by either "0" or "1."
•
"F" reappears on the display and other tests may be chosen.
If an error is detected in any of these four stages, then all control lines are
negated and the relevant error(s) is displayed.

Manual Tests
The manual tests do not generate error codes. The tests do not generate
movement, but allow analysis by software from a manual stimulus of the
respective assembly. These tests may not be used in program mode
3.1.4.1
PSU Control Test (Test 20)
The PSU control test duplicates PSU control just as Test 15. The
difference is that Test 20 is not "intelligent" and does not douse the power
supply on detecting errors. It is also not a simultaneous test. Feedback
signals in this test are displayed real time in a serial fashion. The display
order follows the sequence: IPRESENT, PSOT, HOT, SHORT. Control
lines that latch within this test are indicated in Table 5.
3.1.4.2
Sensor Test (Test 21)
The sensor test reads the state of a sensor. The parameter setting
determines which sensor is chosen. A flashing switch symbol and
conversely a hard on signal indicates a closed (detected) sensor.
3.1.4.3
Encoder Test (Tests 22 and 23)
The encoder test displays the value of a selected encoder. The option is
available to display a particular digit real time or a three-digit snapshot.
3.1.4.4
Form and Function Test (Test 24)
The form and function test setting displays switch status in real time
hexadecimal, which for a VL4 luminaire, at present, is 9 (hex).
