4.17 Carrying out simulation failure of brake element-1 in accordance with EN81-20
In submenu C417 test braking element brake-1 of the DAVID-613 processor system, it is possible to
switch off the monitoring of the braking element of drive 1 for software purposes in order to generate
an error response. This corresponds to a physical interruption of the line of the respective brake ele-
ment. This is required for brake components requiring monitoring, in order to simulate a failure of a
brake element according to EN 81-20.
4.18 Carrying out the brake test
In submenu C418 test brake test of the DAVID-613 processor system, it is possible to activate the brake
test for one trip. After pressing the corresponding key switch S82A or S82B, the stopping distance in
mm is displayed after stopping the elevator car. This function can only be used in conjunction with a
GOLIATH-90 inverter.
4.19 Test direction change counter
In submenu C419 test direction change counter, it is possible to simulate a triggering of the direction
change counter for the suspension cables / carrying straps by test activation.
4.20 Test rope wear counter
In the submenu C420 test rope wear counter, it is possible to simulate a triggering of the rope wear
counter for the suspension ropes / carrying straps by test activation.
4.21 Test brake monitor brake-2
In submenu C421 test brake element brake-2 of the DAVID-613 processor system, it is possible to
switch off the monitoring of the braking element of drive 2 for software purposes in order to generate
an error response. This corresponds to a physical interruption of the line of the respective brake ele-
ment. This is required for brake components requiring monitoring, in order to simulate a failure of a
brake element according to EN 81-20.
4.22 Resetting the speed-gov pre-trigger
In submenu C422 test reset GB pre-shutdown of the DAVID-613 processor system, it is possible to
reset this by activating the function in the case of a lockable pre-shutdown of the GB for the car with
reset coil via pushbutton S50. After releasing the button S50, the function is deactivated again.
When
using SAFE shaft copying, the settings can be viewed in
menu D9.
4.23 Hydraulic-Testdrive – Broken-Pipe-Valve
In submenu C423 Hydraulic test drive – Broken-Pipe-Valve of the DAVID-613 processor system, it is
possible to output the fast speed (V2) by switching on the function for the next run with the return con-
trol in the downward direction. This enables the functionality of the pipe rupture valve to be tested. The
error message “overspeed” is ignored and travel is not aborted.
