C) End of Travel - Braking elements are closing
With drop in braking element, the monitoring time "close monitoring braking element" starts. Within this
time window, it is expected that the braking element is deactivated and the signal exchange is performed
on the brake element monitoring switches:
Brake element monitoring input
Expected status
Configured as Closer
(NO)
0V
Signal level at the monitoring input
Configured as Opener
(NC)
+24V
Signal level at the monitoring input
If the signal change within the time frame, or the synchronization of input channels is not guaranteed,
the control DAVID-606/613/2005 lock with the error message "
F51 brake element function
" or "
F54
brake element synchronization
". Only by
RESET in menu C0,
the controller DAVID-606/613/2005
will be unlocked.
Solely through the on / off switching of the controller, the controller is not unlocked, i.e. if the error
message F51 or F54 is applied and the system shuts off and then switched on again, the control with
the appropriate error message is locked.
1.5.2 Digital Inputs
All these channels can be Inputs-, but also Output-channels. The channels are potential-free about opto
couplers and designed for +24V DC. The inputs can used with the +24V DC Voltage of the inverter or
the +24V DC Voltage of the lift controller (pay attention to the GND connetion to the lift controller !).
The inputs and outputs are freely programmable. The desired input function can be found in the
menu
B72 assignment inputs. For the brake elements are monitoring up to 3 input functions, i.e. it
can monitor up to 3 braking circuits.
Programming of the Digital Inputs
When the brake releases up to 3 independent brake coils can be monitored. The choice of inputs is free,
should the appropriate input functions to be occupied (E25, E438-E439 menu B72).
Assignment of the inputs menu B72
All inputs can be used in principle and are assigned to the features listed below. Assign menu B72 just
as many input channels with features as you have brake circuits.
No.

E25
E25 - Brake Monitoring Coil-1
Input function for Brake Monitoring Coil 1
E438 E438- Brake Monitoring Coil -2
Input function for Brake Monitoring Coil 2
E439 E439- Brake Monitoring Coil -3
Input function for Brake Monitoring Coil 3
1.5.3 Teach in of the Monitoring Times
In the Menu B600 monitoring
the brake members shall be activated. In addition, the switch type (NO
or NC) is defined. With the help of monitoring times, the behavior of the respective braking element type
is adapted.
Brake Monitoring
At the brake monitoring you can look over three brake coils
Brake Monitoring Input
Here you can put the switch-behaviour. There are two possibilities, like
NC-Normally Closed
and
NO-Normally
Open
. Standart value is NC
.
Brake Monitoring Opening
The time needed for the operation of the brake opening a window of up to 2000 ms can be clamped.
Brake Monitoring Closing
The time needed for the process of dropping the maximum brake a time window of 2000 ms are
clamped.
