6.3 Emergency stop
The Emergency Stop button located on the PSU will shut down all system components apart from the
P550 controller when pressed. As a fail-safe, the system must be reset before you can switch on the
system again. Do not reset the system until it is safe to do so. To reset the system ensure the power is
switched off at the main switch. Rotate the Emergency Stop button clockwise and then switch the power
back on. Switch the power off before disconnecting any system components or if the system is not yet
connected.
6.4 Crawler Deployment
Once the system is correctly set-up, you can deploy the crawler in the pipe or conduit you wish to
survey. Care must be taken when deploying the crawler, particularly if it is being deployed into deep
conduits and cisterns via manholes with limited access.
Warning! The
crawlers are heavy! Observe proper lifting procedures when handling, deploying and
removing the crawler. Never lower crawlers or other heavy equipment into manholes while personnel are
working in the manhole.
