Controller Commissioning
Before being placed into service, the controller must be commissioned in order to validate its installation. The
checking of any complete system that the Controller may be installed into, is beyond the scope of this manual. Such
system wide checks must be carried out in accordance with relevant site standards and must include an instruction
or reference to a procedure for commissioning the Controller.
For any system supplied that involves a controller, there will be a commissioning test form. An example of such, is
Ampcontrol document No. GSB010 (a copy of this form is located in appendix A). Test forms for individual
applications will contain aspects of the system that must be checked, part of which will be the Controller.
6.1 Completing a Controller Test Form (Common Header Information)
The specifics of a test form will vary, but recording the following information should be considered standard
across all applications:-
Job number related to the commissioning.
Customer Name.
Location of the controller (site address and location on the site, system type, e.g. continuous miner etc.)
Product Type (Version of Controller also included).
Serial Number.
Name of person carrying out the commissioning.
Date.
References to site specific restrictions and applicable standards.
6.2 Running through a Controller Commissioning (Refer to the example test sheet
in appendix A)
The actual setting that the controller must have will have been defined at either the system design phase or between
the time of the Controller installation and the first power up (commissioning) phase. Although shipped with a set of
default values, each individual application will requires adjustments to the configuration settings.
If configuration is to be carried out with the Controller in-situ, it may be beneficial to disconnect all relay connections
and current follower connections, to prevent unwanted system interactions.
6.2.1 From first power-up, the following operations can be checked immediately:-
1. Power LED illuminates.
2.
All LEDs illuminate and display indicates ‘SELF TEST IN PROGRESS’
[a]
3. After 4 seconds, display indicates ‘DELAY’
[b]
in the display window for each enabled channel. Alarm and
Fault LEDs extinguish. RL1, RL2, RL3 and RL4 LEDs illuminate.
4. Delay expires and display indicates channel readings. If relays have been set to LATCHED power up
mode, then all relay LEDs will remain illuminated once the start-up delay expires. An alarm reset is required
to clear the states of relays that start up in latched mode.
[a] The self test phase of the Controller checks the integrity of the system configurations and memory
read/write integrity. If the memory check fails, the Controller will pulse all LEDs on and off and
toggle the state of all four relays on a 1 second on, 1 second off cycle. If this occurs, contact
Ampcontrol.
[b] The Controller start-up delay, delays the action of processing channel input signals, thereby
allowing connected equipment to establish stable working conditions after power-up. During this
time, the Controller’s alarm relays are held in an alarm state.
