2. 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, signalling overspeed,
underspeed, zero motion and the direction of rotation. Units providing an analog 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 input formats and programmable
monitoring functions.

4.6. Power Supply
The units require a DC supply from 17 to 30 V 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 V input (plus encoder currents taken from the auxiliary
voltage output).
4.7. Auxiliary Output for Encoder Supply
Terminals 4 and 3 provide a +5.2 VDC / 200 mA auxiliary output for supply of encoders and
sensors.
4.8. Impulse Inputs for Encoders and Sensors
The setup menu of the unit allows individual setting of the desired characteristics of the signal
inputs. According to the application the units will accept single-channel signals (input A only with
no direction information) as well as dual channel signals A/B including information of the
direction of rotation. The following input formats and levels are acceptable:
symmetric differential input with RS422 format A, /A, B, /B
asymmetric (single-ended) TTL levels (A and/or B only without inverted channels)
HTL level 10 ... 30 V, alternatively differential (A, /A, B, /B) or single-ended
(A and B only, without inverted channels)
Signals from proximity switches or photocells providing HTL level (10 ... 30 V)
NAMUR (2-wire) signals
4.9. 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)
Dz260_05a_oi_e.doc / Dez-16 Page 14 / 40
4.10. 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

4.11. Relay Outputs K1 – K3 (DZ260 and DZ267 only)
The units provide three programmable relay outputs (all dry changeover), providing a switching
capability of 30 V / 2 A DC or 125 V / 0.6 A AC or 230 V / 0.3 A AC. Both, switching
characteristics and monitoring function may be programmed for each of the relays individually.
4.12. Transistor Outputs K1 – K3 (DZ261 and DZ269 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 V / 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.
4.13. Scalable Analog Output (DZ260, DZ261 and DZ266 only)
The units provide a voltage output with a +/-10 V range (max. load 2 mA) and a current output
with ranges 0 / 4 ... 20 mA (burden 0 – 270 Ohm), however only one of the two can be used at a
time. Beginning and end of the desired conversion range can be set by the operator menu (see
section 7.2.7). The common potential of both outputs refers to GND.
The total resolution is 14 bits. A settling time of approx. 200 µs. is required. The overall response
time of the analog outputs primarily depends on the selected Sampling Time setting. After
volatile jumps of the input signal, the analog outputs may need up to two Sampling Time cycles
(plus 200 µsec.) to stabilize.
Important note: “voltage out” and “current out” must not be used together.
Please do never connect mA and V simultaneously!
Dz260_05a_oi_e.doc / Dez-16 Page 15 / 40
5. LCD Display and Keys
The units provide a back-lit LCD display 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)
Actual switching states of relays/transistor outputs
(Rel1, Rel2, Rel3)/(out1, out2, out3)
C = Closed, O = Open
I: Inputs
Actual 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.
Dz260_05a_oi_e.doc / Dez-16 Page 16 / 40
6. 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 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
6.1. 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"
6.2. Keypad Interlock
There is a 3-stage conception to protect the keys against unauthorized changes of the
configuration respectively against activation of commands.

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 6.6)
c) or change the parameters being responsible for the locking by PC

6.3. 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.

6.4. 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 colour and indicate the cursor position.

6.5. 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).
6.6. 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
When execute this action, please be aware that all parameter settings
will be lost and the whole setup procedure must be repeated!

7. Menu Structure and Parameter Description
All parameters are combined to groups, arranged in several menus. Settings are only necessary
for parameters which are really relevant for the individual application.

(*) With settings HTL / NPN the input terminals are connected to the power supply voltage of
the unit (+24 V) via internal pull-up resistors. For this reason it is advisable to first set the
encoder properties correctly, prior to connecting TTL encoders to the unit.
Setting HTL / NPN is also suitable for use with NAMUR (2-wire) proximities.
(connect the positive wire of the sensor to the input terminal and the negative wire to GND)

7.2.3. 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 analog
output, i.e. a range from 0 to 10 000 units corresponding to 0 - 100,00 % of the full scale output
(see section 7.2.7 "Analog Menu"). This readout can still be rescaled to user-friendly engineering
units, using the following parameters:

The definition of the "Basic Value" occurs in the "Analog Menu" and is also available
for the DZ267 units without analog 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

7.2.8. Serial Menu
Serial transmissions will operate in either the “PC Mode“ or in “Printer Mode“.
With “PC-Mode“, the unit receives a request string and responds with a corresponding data
string. For details of the protocol see separate description “SERPRO“.
With “Printer Mode“ the unit sends data without any request and under Timer control as
described subsequently.
As soon as the unit receives a character, it automatically switches over to PC Mode and operates
according to protocol. When for a period of 20 sec. no character has been received, the unit
switches automatically back to “Printer Mode“ and starts cyclic data transmission again.

8. Example for Commissioning
The following example is to explain setup and commissioning of the units with a typical
application.
A tooth wheel with 32 teeth should be monitored with respect to speed and standstill
For speed pick-up we use two proximity switches "Namur-type", which for detection of the
direction of rotation are mechanically displaced to generate an impulse offset
Relay 1 should signal "standstill" when one second after detection of "zero frequency" no
further input impulse has been registered
Relay 2 should generate a timed output pulse of 0.3 seconds when the speed drops below
100 RPM in either forward or reverse direction.
Relay 3 should switch on and catch when, with forward direction only, the speed exceeds
300 RPM. With reverse direction relays 3 should not respond at all
Release of the relay 3 catch state should be possible by either a positive signal applied to
input "Control1", or by activating the ENTER key.

9. Appendix
9.1. Hints for Use of the Linearization Function
The linearization function of these units allow to convert a linear input frequency into a non-linear
developing, which can be indicated on the LCD display and which is also available as analog
signal or as serial data, for further processing.
There are 16 programmable x/y coordinates available, which can be set in any desired distance
over the full conversion range. Between two coordinates, the unit uses linear interpolation.
Therefore it is advisable to use more coordinates in a range with strong curves and only a few
coordinates where the curvature is less.
To specify an individual linearization curve, the „Linearisation Mode“ register must be set to
either 1 or 2.
The registers P1(x) to P16(x) are used to specify the coordinates on the x-axis. These are the
measuring values that the unit normally would generate according to the actual input frequency.
These settings must be in % of full scale.
Now enter the attached values to registers P1(y) to P16(y). These are the values that the unit will
generate instead of the x- values, i.e. P2(y) will substitute P2(x) etc.
x-registers must use continuously increasing settings, i.e. P1(x) must
have the lowest and P16(x) must have the highest setting
All entries use a percental format of xx.xxx% full scale.
Setting 000.000 % means zero output and setting 100.000 % means
full scale output.
With Linearisation Mode set to 1, it is a must to set P1(x) to 0 % and
P16(x) to 100 %. Linearisation is defined in the positive range only
and the negative range will be a mirror image of the positive range
with reference to zero.
With Linearisation Mode set to 2, it is a must to set P1(x) to –100 %
and P16(x) to +100 %. This enables the user to set curves which are
not symmetric to the zero position.

9.2. Data Readout via Serial Interface
All register codes shown in the "Serial Menu" are available for serial readout by PC or PLC. For
communication the monitors use the Drivecom Protocol according to ISO 1745. All protocol details
can be found in our manual SERPRO_2a.doc which is available for download from our homepage
www.motrona.com.
To request for a data transmission you must send the following request string to the converter:
EOT
AD1
AD2
C1
C2
ENQ
EOT = control character (Hex 04)
AD1 = unit address, High Byte
AD2 = unit address, Low Byte
C1 = register code, High Byte
C2 = register code, Low Byte
ENQ = control character (Hex 05)
The following example shows the request string for readout of the actual input frequency of a
monitor (code :9) from a unit with unit address 11:
ASCII Code:
EOT 1 1 : 9

0011 0001

0000 0101
After a correct request, the unit will respond:
STX
C1
C2
x x x x x x x
ETX

STX = control character (Hex 02)
C1 = register code, High Byte
C2 = register code, Low Byte

9.3. “Relay Action”, override relay states by programmed states
Models providing relay outputs allow to temporary change the actual relay states according to a
programmable ON / OFF pattern, or to temporary freeze the actual switching states. These
override functions can be activated by either touching a front key or by a remote command.
9.3.1. Override relay/output states by programmable ON / OFF states
Parameter “Relay Action” allows to select which of the relays/outputs should be affected by the
override action. Parameter “Action Polarity” provides setting of the desired “ON / OFF” pattern»
(see section 7.2.9, “Switching Menu”). The desired way of activation this override command can
be set by the “Command-Menu” (see 7.2.6).
Application example:
You would like to temporary de-energize relays K1 and K3 by touching the key “UP”, whilst relay
K2 should continue to function normally.
Action
Parameter settings
1
Assign the Override Command to key “UP”
Key Up Func. = 2
2
Select relays/outputs K1 and K3
Relay Action = 5
3
Set the desired switching state of the
relays/outputs (both de-energized)
Action Polarity = 2
9.3.2. Freeze the actual switching state of all relays
This function will temporary freeze all relays in their actual state for the duration where you press
a key or apply a remote command. During the freeze period the relays will no more follow any
changes of the input frequency
Application example:
You would like to freeze all relays by applying a “High” signal to input “Control1”
Action
Parameter settings
1
Assign the Freeze command to input “Control1”
Input 1 Func. = 2
2
Set the input to “Active High” characteristics
Input 1 Config = 1
3
Assign the “Freeze relays” function to the input
Relay Action = 8
These commands will override the switching states of the selected relays/outputs. All
relays/outputs will immediately return to the actual control state after removing the
override command. All internal measuring and control cycles will continue normally.
To use these functions, please set the corresponding key and input characteristics to
static operation only, since dynamic (edge-triggered) operation would make no sense
Dz260_05a_oi_e.doc / Dez-16 Page 38 / 40
9.4. Monitoring of remote motion enable signals
The unit provides a special "Command Monitor" function for logical control of a motion enable
signal and the resulting response of the system. In addition to the normal monitoring functions
this mode is suitable to generate alarm outputs under any of the following conditions:
motion is disabled, but still the system moves
motion is enabled, but the system does not move at all (mechanical deadlock), or the
system does not reach the scheduled speed within an expected time (overload)
the motion command changes over from "enable" to "disable" but the system does not come
down to standstill within an expected time
The following parameter settings will activate the Command Monitor function:
9.4.1. Definition of a speed window
The application requires one of the relays to operate in overspeed mode (Preselect Mode = 0) and
another relay to operate in underspeed mode (Preselect Mode = 1). This will define a window for
the expected speed under regular motion conditions (see 7.2.9)
9.4.2. Assignment of a control input
One of the two control inputs has to be set to the control function "12" to activate the monitoring
of the command. This input must be connected to the remote Enable/Disable signal (see
parameters "Input Function" under 7.2.6)
9.4.3. Assignment of the control polarity
Parameter "Input Config" provides setting of the input polarity as follows:
Input Config = 0 => Motion disabled (stop) corresponds to input level "LOW"
Motion enabled (run) corresponds to input level "HIGH"
Input Config = 1 => Motion disabled (stop) corresponds to input level "HIGH"
Motion enabled (run) corresponds to input level "LOW"
9.4.4. Setting of a Start-up delay time
Any signal changes from "disable" to "enable" or vice-versa will require some delay until the
system could really follow the command (acceleration or deceleration). Therefore it is mandatory
to set an appropriate start-up delay time (to the relay/output responsible for "underspeed" only).
See section 7.2.9 “Start Up Mode" and "Start Up Relay".
9.4.5. Setting of an appropriate Standstill definition
Under parameter "Standstill Time" an appropriate time must be set (see section 7.2.9).
The command monitor uses always the same relay/transistor output to which the
underspeed function has been assigned.
It is important to set a time higher than the Start-up delay time!
While the command monitor function is active, you can see an indicator box in the
PI/PO column of the PC screen. The "Command Monitor" box shines blue when the
motion command is in "Disable" state.
