3.3.3 Extra requirements for UCM testing of hydraulic
elevators
Hydraulic elevators use special valves to satisfy EN 81-
2+A3. These can only be checked for proper functioning us-
ing the "with drive unit" setting in the testing program.
The used valves are monitored during normal operation.
Depending on the manufacturer, there are one or two out-
puts which are monitored by the control system. In order to
check these for flawless operation, the inputs on the control
system must be disconnected and/or provided with a con-
tinuous signal (24 V). The system module detects an erro-
neous sequence of signals in normal operation and blocks
while displaying a corresponding error message.
3.3.4 Entries in stack memory
The maintenance stack shows two entries after every test
"UCM test (A3) starting" and "UCM test (A3) terminated",
so that both processes are documented. The release of
blocking conditions is documented in the message stack. In
this regard, it is differentiated whether the block was lifted
via terminal or menu.
