Action to be Performed
9)
7.3.9 Use the commissioning screen to check the operation of each
detector is correct.
MOVAComm uses highlighting to indicate detector active.
Also check that vehicles in adjacent lanes do not activate the loop.
10) 7.3.9
Important:
The following causes the MOVA unit to take control of
the Intersection and care should be taken to avoid undue disruption
to traffic flows.
Still using the commissioning screen, force each stage in turn and
check that the controller moves to the required stage and that the
correct stage / phase confirm bits are activated.
11)
7.3.10 Check that the Error Log contains no unexpected entries and then
clear the error log.
12)
7.3.11 Again using the commissioning screen, put the MOVA unit on
control:
a) Set the ‘MOVA enable’ flag to ‘1’ *
b) Close communications (‘
FI
’ from the menu)
c) On the outstation web interface, ‘System’ screen, stop the
MOVA application and then start it again.
d) Restart MOVAComm and return to the commissioning screen
13)
7.3.11 Check that as the controller changes from stage to stage that the
‘Warm-up Count’ increments.
When this count reaches the number of stages plus one (e.g. 6 on a
5-stage controller) the MOVA unit will put itself on control. Check :
a) The ‘On Control’ flag changes from ‘0’ to ‘1’.
b) The ‘TO’ bit changes from ‘0’ to ‘1’.
c) The MOVA unit demands the current (or next) stage.
d) The ‘Error Count’ remains at zero.
e) The UTC ‘MR’ and ‘ML’ reply bits are active.
14)
7.3.11 Examine the operation of the controller under MOVA control to
ensure that reasonable operation is achieved, e.g. no demands are
been ignored and no excessive queues build-up, and that no faults
have been generated and the error count remains at zero.
15)
7.3.12 This completes the commissioning steps. Restore the UTC MO
signal to its normal state and check that UTC takes control of the
junction. The MOVA unit can, depending on the client’s instructions
and the validity of the data, be left operational.
Note that for highly critical junctions where the loss of a detector
without the historical flow data could result in serious complications,
it may be necessary to leave the MOVA disabled for one week.
When the unit has built-up this back-up data, the unit can be
enabled. Note that the unit can be enabled remotely if a telephone
line is fitted.
