1. Introduction DZ210 has been designed as a monitor module for assembly in electrical control cabinets. The units are suitable for monitoring the direction of rotation and the zero-motion state with industrial machine applications. As remarkable properties, the DZ 210 units provide a very high input frequency range, a very fast response time and versatile settings for encoder characteristics and evaluation of the signals with respect to direction and standstill detection. 2.

2.1. Power Supply The unit operates with a DC power from 17 to 30 V, applied to terminals 1 and 2 of terminal strip X4. The power consumption is approx. 30 mA (plus about 30% of the current taken from the auxiliary 5 V output) 2.2. Auxiliary Power output Positions 8 and 9 of terminal strip X4 provide an auxiliary, stabilized 5 VDC output. The real output voltage is a little higher (e.g. 5.4 V) in order to compensate for voltage drop on connectors and cables.

2.6. Transistor Outputs Both transistor outputs "Out1" und "Out2" (terminal X3) operate in parallel to the relay functions, but respond much faster (200 µsec only) than the relays. The outputs are rated to switch DC voltage from 7 - 30 V at maximum currents of 350 mA (each). The transistor outputs are 100% short-circuit-proof, however not both outputs must be shortcircuited at the same time for a longer duration. 2.7.

More combinations can be set with consideration of the individual function of each switch position, according to the following table: 1 OFF: HTL level (all of the 4 input lines) ON: TTL level (all of the 4 input lines) 2 OFF: Input B is symmetric (needs /B) ON: Input B is asymmetric (single-ended, no /B) 3 OFF: Input A is symmetric (needs /A) ON: Input A is asymmetric (single-ended, no /A) 4 --ON: internal pull-up resistor towards + *) 5 --ON: internal pull-down resistor towards GND *) *) Positions 4 and 5

T T (1) (2) = Standstill signal OFF = Standstill signal ON 3.3. Setting of the Standstill Time (T) Provided that the standstill function has been assigned to relay 2 and output 2 by setting DIL switch 1 position 7 to ON, a standstill definition can be set by means of positions 1 - 4 of the switch DIL 2. The table indicates the pause time between two input pulses that must be exceeded in order to signal "standstill".

3.4. Definition of Direction of Rotation In order to achieve a stable indication of the actual direction of rotation even under vibration and mechanical oscillation, positions 5 - 8 of switch DIL 2 provide setting of an impulse window. Before detecting a direction or changing the direction signal, the unit must receive a consecutive number of impulses in the corresponding direction. The table shows how to set the switches to define the number of impulses required for detection of the direction.
PAGE 10
The drawing below explains the operation of the direction outputs upon a change of direction. With case (1) the window has been set to 1 impulse only. As a result the unit immediately changes the output already after the very first impulse into the opposite direction. With case (2) a window >1 has been set, wherewith the short change of the phase between channels A and B does not affect the direction signal. Channel A Channel B (1) (2) = Forward motion DZ21001b_e.
