Operation modes and Commissioning
11.1.5 Test Mode
Test mode can only be entered from normal mode. This is done by the corresponding CANopen command.
The test mode provides the following sub modes:
Idle
Trip
ETSL-UP
ETSL-DOWN
Pre-trig
Immediately after entering test mode the sub mode “idle” is activated. In sub mode idle, the behavior of the
safety functions is the same like in normal mode. Concerning the other sub-modes, the behavior of each one
safety function is changed for test purposes. For details refer to the next sub-chapters. Each of these sub modes
can be entered by the CANopen demand to change to the corresponding sub-mode, provided the device is still
in test mode.
Test mode can only be left with transition to normal mode. This is done by the corresponding CANopen com-
mand. This can be also done by a system RESET or power cycle.
11.1.5.1 Test Mode, Sub-Mode “Trip”
Sub mode trip can be entered by CANopen command to change the sub-mode to “trip”.
In sub-mode “trip” the final tripping speed for the safety function “Overspeed final tripping” is set to a reduced
value. This value must be smaller than the normal final tripping speed. The value for the test final tripping speed
is same as the rated speed by default. This value can be changed via CANopen in normal mode (before sub-
mode “trip” is entered).
If the test final tripping speed has been set to a value bigger than the normal final tripping speed, the CANopen-
demand to enter sub-mode “trip” will be refused.
If the test final tripping speed is set to a value smaller than the normal final tripping speed, the CANopen-
demand to enter the sub-mode “trip” will be successful. In sub-mode “trip” the safety function overspeed final
tripping already trips at this reduced test final tripping speed.
OC will open latest at the same speed than eSGC in sub-mode ”trip”.
So, if test final tripping speed is below the normal pre-tripping speed, OC will open at the same speed as eSGC
during the test.
If the value of test final tripping speed is between the normal pre-tripping speed and the normal final tripping
speed, the opening of OC will take place at the normal pre-tripping speed.
The whole other functionality is identical to normal mode.
If test mode sub mode trip is entered, normally a test of over- speed final tripping will be performed. A lift travel
e.g. with rated speed will be initiated and over- speed final tripping will trip due to the reduced tripping speed.
After tripping of over-speed final tripping a RESET is necessary. After RESET the safety function will be reset and
LIMAX33 CP-00 will restart in normal mode.
But this test-mode, sub-mode trip, can also be left explicitly transition to normal mode, initiated by CANopen
command.
