1. Introduction
This new series of monitors has been designed as control modules for mounting inside of
electric control cabinets. The units are suitable for speed monitoring of machines, signaling
overspeed, underspeed, zero motion and the direction of rotation. Units providing an analogue
output can moreover be used for closed-loop control or feedback purpose within a control
system.
Very special advantages of these new monitors are the wide frequency range, the extremely
fast response and the remarkable versatility with regard to possible programmable monitoring
functions.
2. Available Models
There are five models available, all with fully similar basic functions, but with different options
concerning the outputs.

3.1. Power Supply
The units require a DC supply from 17 to 30 volts which must be applied to terminals 1 and 2.
Depending on the input voltage level and internal states, the power consumption may vary and
lies in a range of about 70 mA with a 24 volts input (plus encoder currents taken from the
auxiliary voltage output).
3.2. Auxiliary Output for Encoder Supply
Terminals 4 and 3 provide a +5.2 VDC / 200 mA auxiliary output for supply of encoders and
sensors.
3.3. Inputs for SinCos Encoders and Sensors
The encoder shall be connected at the screw-type terminal 5-8 of the device. Only encoders
with differential sine-cosine signals of 1 Vpp can be used (0.8 Vpp - 1.2 Vpp). At any time the
signals sin+/sin- and cos+/cos- must be available.
Pins 3 (GND) and 4 (+5,2 V) of the screw-type terminal provide an auxiliary power output for the
encoder supply.
3.4. Control Inputs
Two programmable control inputs allow the assignment of functions like remote start-up-delay,
reset of relay lock, hardware interlock of the keypad and similar.
Both inputs provide PNP characteristics and require HTL level. Also it is possible to set the
control function to "active LOW" or "active HIGH".
For evaluation of dynamic events the desired "active edge" can be set (rising or falling edge)

DZ27001a_e.doc / Jan-13 Page 11 / 36
3.5. Serial Interface
The serial RS232 interface in general may be used
for easy setup and commissioning of the units (with use of the OS32 operator software)
to change settings and parameters by PC or PLC during the operation
to read out internal states and actual measuring values by PC or PLC
The subsequent drawing shows how to link the monitor with a PC, using the standard
9-pin Sub-D-9 connector

3.6. Relay Outputs K1 – K3 (DZ270 and DZ 277 only)
The units provide three programmable relay outputs (all dry changeover), providing a switching
capability of 30 volts / 2 amps DC or 125 volts / 0.6 amps AC or 230 volts / 0.3 amps AC. Both,
switching characteristics and monitoring function may be programmed for each of the relays
individually.
3.7. Tansistor Outputs K1 – K3 (DZ271 and DZ 279 only)
The units provide three outputs with programmable switching characteristics.
K1 – K3 are fast-switching and short-circuit-proof transistor outputs with a switching capability
of 5 – 30 volts / 350 mA each. The switching voltage of the outputs must be applied remotely
to the Com+ input (terminal 22). Both, switching characteristics and monitoring function may be
programmed for each of the outputs individually.
3.8. Scalable Analogue Output (DZ270, DZ271 and DZ 276 only)
The units provide a voltage output with a +/-10 volts range (max. load 2 mA) and a current
output with ranges 0 – 20 mA respectively 4 – 20 mA (load 0 – 270 Ω). Beginning and end of
the desired conversion range can be set by the operator menu. The common potential of both
outputs refers to GND.
The total resolution is 14 bits. A settling time of approx. 200µs. is required. The overall
response time of the analogue outputs primarily depends on the selected Sampling Time
setting. After volatile jumps of the input signal, the analogue outputs may need up to two
Sampling Time cycles (plus 200 µsec.) to stabilize.

DZ27001a_e.doc / Jan-13 Page 12 / 36
4. LCD Display and Keys
The units provide a back-lit LCD displays with 2 lines at 16 characters each, and four keys for
setup and command control.
During the setup procedure the LCD display indicates the menu with all parameter texts and the
set values of the parameters.
During normal operation, the LCD display indicates the following information:
Actual speed value
Input frequency, scaled in user units
+156.5 Hz
I: LH O: COO +47 %
Analogue output (not with DZ267, DZ269)
Actual output level in % of full scale
O: Outputs (not with DZ266)

(Rel1, Rel2, Rel3)/(out1, out2, out3)
C = Closed, O = Open
I: Inputs
aktueller logical state of inputs
(Control1, Control2)
L = Low, H = High
The "Display Menu" allows free scaling of the speed measuring values and the speed-related
parameters to any kind of engineering units.

DZ27001a_e.doc / Jan-13 Page 13 / 36
5. Keypad Operation
A summary of all parameters and a detailed description of parameter functions is available
under section 6.
For all operation, the units provide four front keys which subsequently will be named as shown
below:
PROG
UP
DOWN
ENTER
The key functions depend on the actual operating state of the units. Basically we have to
distinguish between Normal Operation and Setup Operation
5.1. Normal Operation
While in normal operation state, the units monitor the speed according to the selected
operational parameters and settings. Each of the front keys provides the command functions as
attached to it upon setup in the "Command Menu"
5.2. Keypad Interlock
There is a 3-stage conception to protect the keys against unauthorized changes of the
configuration respectively against activation of commands.
Stage Protected
Range
Protection
by
Key Operations
Change of Parameters Commands
1--- --- permitted permitted
2Menu Password upon
activation of menu
Protection of selectable parts of the menu
via password
permitted
3Keyboard Hardware-Latch 1 interlocked permitted
Hardware Latch 2 All functions interlocked
The "Key Pad" menu allows to define an individual password for each group of parameters. This
function can be used to provide individual access rights to different operators. Upon access to
an interlocked section the unit asks for the corresponding password. If the correct password is
not entered in time, the unit denies access and automatically returns to normal operation.
The hardware latch function can be activated and deactivated by one of the Control Inputs, or
by means of serial access to the corresponding locking register.
Using the Hardware Latch function may accidentally cause a total locking of all
functions, when the Control Inputs characteristics have been set inauspiciously.
In this exceptional case you can release the key functions again by either
a) applying the correct logical state (High or Low) to the inputs
b) or resetting the parameters to their default values (see section 5.6.)
c) or change the parameters being responsible for the locking by PC
P

DZ27001a_e.doc / Jan-13 Page 14 / 36
5.3. General Setup Procedure
To change over from normal operation to the setup state, please keep down the PROG key for
at least 2 seconds. After this the menu appears and you can select one of the menu groups.
Inside each group you can select the desired parameter and edit the setting according to need.
After this you are free to edit more parameters, or to return to normal operation.
The function of the different keys during setup is shown in the table below.

5.4. Changing Parameters on the Setting Level
With signed parameters, the front digit can only be changed between „+“ (positive) and „-„
(negative). The subsequent example explains how to change a parameter from originally 1024
to a new value of 250 000.
The example assumes that you are already on the Setting Level, i.e. you have already selected
the corresponding parameter and read its actual value on the display. Highlighted (blinking)
digits are marked by background color and indicate the cursor position.

5.5. Return from the Menu, Time-Out Function
At any time the PROG key changes the Menu by one level backwards or fully back to the normal
operation mode. The menu also switches automatically one level backwards, every time when
for 10 seconds no key has been touched (Time-Out-Function).
5.6. Reset all Parameters to Factory Default Values
If applicable, the whole set of parameters can be reset to factory default values (e.g. because a
code for the keypad interlocking has been forgotten, or because the unit does no more work
correctly for reasons of bad settings). All default values are indicated in the following
parameter tables.
To execute this Reset procedure, you have to take the following steps:
Power the unit down
Press
and
simultaneously
Switch power on with both keys held down
Where you decide to execute this action, please be aware that all parameter
settings will be lost, and you will have to repeat the whole setup procedure

6. Menu Structure and Parameter Description
All parameters are combined to groups, arranged in several menus. You must only set those
parameters which are really relevant for your individual application.
6.1. Survey of Menus
This section provides an overview of the menus and their assignments to the different functions
of the units. The menu names are printed bold, and associated parameters are arrayed directly

6.2. Parameter Descriptions
6.2.1. Preselections
Preselection parameters are not relevant for model DZ276
These parameters assign the desired switching points to the relays/outputs. The preselections
use the same engineering units as the display of the actual speed (see Display-Menu).

6.2.3. Serial Readout Menu
An actual value proportional to the input frequency can be read out via serial link, accessing the
serial readout register (code :8 ) As a Basic Value this register uses the scaling set for the
analogue output, i.e. a range from 0 to 10 000 units corresponding to 0 - 100,00% of the full
scale output (see "Analogue Menu"). This readout can still be rescaled to user-friendly
engineering units, using the following parameters:

Code
Setting Range
Default
Multiplier
„A8“ -99999…99999 10000
Divider
„A9“ 0…99999 0
Offset
(absolute term) „B0“ -99999999…99999999 0
Readout (:8) = Basic Value x
Multiplier
Divider
+ Offset
The definition of the "Basic Value" occurs in the "Analogue Menu" and is also
available for the DZ277 units without analogue output
the ratio Multiplier / Divider must never be greater than 15 000
Setting "Divider" to zero will skip the rescaling procedure, resulting in a shorter
response time with all functions of the unit
More details about serial communication can be found in the appendix.
