1. About this manual
1.1 General
The CBM Handbook is a comprehensive reference work for the experienced elevator expert.
Objectives of this manual:
➢Describe the technical data of the CBM
➢Describe the operation of the CBM
➢Describe the configuration of the CBM
➢Describe the messages of the CBM
The CBM is a module that can control brake coils of all voltages (40-200VDC) and currents (up to 4A) up to a power
of 240VA without protection. It is type-tested according to DIN EN81-20. In addition, it can perform brake test and
evacuation (for machine roomless systems). In addition, other functions are available, such as the connection of a
motor PTC or brake monitoring. The function of the brake circuits is monitored by a continuous current measurement.

4.3 Explanation of inputs
4.3.1 DRIVE-Signal
The DRIVE-Input can handle voltages from 48-230VUC. As a result, all common safety circuits can be connected
here. This signal opens two safety contacts in front of and behind the brake and thus prepares the power supply of
the brake coil. If brake coil 3 is connected, which is intended for the transmission of the elevator motor, then this is
also opened directly with the DRIVE signal.
4.3.2 BRAKE-Signal
The BRAKE signal opens brake 1 and 2 if both are activated. These two brake coils are mounted on the traction
motor.
4.3.3 EVAK-Signal
The EVAK signal is used for evacuation in the event of a fault. It activates a different measurement of the input
voltage, since the evacuation can also be carried out with a UPS as power supply. When the EVAK signal is
activated, normal driving is not possible!
4.3.4 Test-Signal
With the test signals 1-3, either the brake test or the evacuation can be performed.
In addition, by pressing T1 and T2 during the boot process, the EEPROM can be reinitialized with the default values.
For details, see section 4.6.
A detailed description of the signal sequences can be found in Section 4.5
4.4 Explanation of Outputs
4.4.1 OK-Signal
The OK output signals that the CBM is active and has no error. This output is only active if both processors (control
and monitor CPU) release them.
4.4.2 Open-Signal
The open output signals an open brake.
4.4.3 Test-Signal
The test output signals an active brake test.

_________________________________________________________________
Handbuch CBM 15
4.5 Sequence of the control
4.5.1 Normal ride
During normal driving, only the DRIVE and the BRAKE input are activated. DRIVE must be applied first. In this case,
if connected, the brake 3 is opened. Then BRAKE is applied. This opens brake 1 and 2. After the ride BRAKE is
deactivated again. Then first brake 1 and 2 close. Thereafter, brake 3 is closed. Now DRIVE must be deactivated
again. The inputs DRIVE and BRAKE are checked with an ABC circuit. This means that DRIVE must be
activated before BRAKE and both signals must be deactivated before reactivation!
4.5.2 Emergency stop
During emergency stop, the DRIVE signal is deactivated first. As a result, all brakes are immediately closed! In this
case, no voltage ramp is driven!
4.5.3 Brake test
In the brake test, a normal ride is first initiated. By activating the respective test signal, the corresponding brake is
closed immediately. The other brakes remain open. The brake test is signaled directly via the test output to the
controller of the lift. This must now ensure that the torque is removed from the frequency converter. As a result, it will
disable the BRAKE signal. This is allowed for the brake test. The other brakes remain open anyway. The other
brakes only close when the DRIVE signal is deactivated.
4.5.4 Evacuation
To perform an evacuation, the EVAK signal must first be activated. This changes the internal control of the brakes,
since the evacuation can also be performed with a UPS. Since it is also possible to use UPSs that do not generate a
pure sine wave voltage (VI-SY-333 or better), the phase control must be adjusted. Now the brakes are controlled by
the previously stored operating current.
Now the DRIVE signal can be activated. As a result, brake 3 already opens when it is connected. By activating the
signals Test 1 and Test 2 the evacuation can be activated. This is carried out in the mode set via the dip switches
(pulse and period duration). If you deactivate the signals again, the brakes come back in.
4.6 EEPROM
The EEPROM mainly stores data required for the CANopen functionality. For details, see the CANopen manual.
In addition, the operating currents of the individual brake coils are stored here. These are necessary to perform an
evacuation. The default value for all brakes is the equivalent to 0.4A. If this value is still in the EEPROM and a normal
ride is triggered, the current values of this normal travel are stored and used in the following. Thus, an evacuation
with a CBM in factory settings without prior normal drive would have a current control to 0.4A per brake result. After a
single normal ride a correct evacuation is possible!

5.2 Status-LEDs
Each of the two integrated controllers has a 2-color LED (blue / red). The meaning of the states is different.
5.2.1 Status Monitoring
Blue LED:
•On: Monitoring OK
•Off: Monitoring not OK
Red LED:
The red LED indicates a fault condition. It can show a 5-digit error code by flashing. The duration of a job is 1000ms.
A logical 1 has an on time of 500ms while a logical 0 only has an on time of 100ms. To find the beginning of the 5-
digit code, there is a break of 2000ms between the end and the beginning.
