Step Section Action to be Performed
18) 9.6.10 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) Switch the MOVA unit’s power off and back on
d) Return to the commissioning screen
Check that as the controller changes from stage to stage that the
‘Warm-up Count’ increments.
* MOVA cannot be enabled if the licence number is invalid (9.6.5).
19) 9.6.10 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.
20) 9.6.10 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.
21) 9.6.11
Telephone Options
The MOVA unit can be installed with various telephone line options:
a) Older MOVA units share a single telephone line with a separate
Siemens OMCU, see section 9.4.
b) In a new ‘Integrated OMCU and MOVA unit’, the OMCU
application is always responsible for dialling the RMS Instation.
This would have been checked during the OMCU
commissioning sequence.
c) The MOVA unit can also function without a telephone line.
For both options a) and b), the telephone line should have already
been checked as part of commissioning the OMCU. Therefore, no
additional telephone tests are required for MOVA.
22) 9.6.12 This completes the commissioning steps. The MOVA unit can be
now be left to control the traffic.
Note that for highly critical junctions were 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 with
the controller running in its fall-back mode. 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.
