This manual describes the „migan“ and „migra“ LED large format display
with pulse counter. The following inputs are integrated:
2 counting inputs or counting input and counting direction (pulse
counter) or input for incremental position encoder (2 phase-delayed
signals)
Reset- and preset input
The configuration of the counter happens with the help of a PC software
(communication with the PC via USB interface).
With the help of BCD coded inputs, settings like the preset value of the
counter or overflow and underflow values can be changed within running operation.
It is possible to control external peripherals like LEDs, horns etc. with the two
available relay outputs (optional).
Display options:
Counting value
Frequency
Number of revolutions
Cycle duration
Time
Display type: 7 segment LED (migan), LED dot matrix (migra)
Digits: 1 to 100 Decimal point: configurable position
View: single or double sided
Inputs: 2 pulse inputs,
Second pulse input can be configured as input with
counting direction,
inputs for phase-delayed signals pulses (input for
incremental encoder (TTL))
Reset/preset input,
4 inputs (migan controller),
Optional preset inputs BCD
Outputs: 4 outputs (migan controller)
Cut-off frequencies: can be configured with MKS software
10 Hz, 100 Hz, 1 kHz, 10 kHz, 100 kHz, >1 MHz –
max. 2 MHz
Input level: adjustable with MKS software
(pulse input) 5 V, 10 V, 12 V, 15 V, 24 V, 36 V, Pull-up to 5 V
Input level: adjustable with MKS software
(Reset/preset) 5 V, 10 V, 12 V, 15 V, 24 V, 36 V, Pull-up to 5 V
Input level: U
(incremental input) U
Display options: counting value,
frequency (counting pulses per time unit),
number of revolutions,
cycle duration,
speed (incremental input),
customer-specific
Dimensional display: upon request
Operation voltage: 230 V / 50 Hz, 110 V / 60 Hz or 24 VDC +/-20 %
Housing: industrial version, powder coated aluminium
Mounting: articulated arm, hanging with chain, angle brackets
Protection: IP54 or IP65
Operating temperature: 0 to +50 C (optional -20 to +50 °C)
Storage temperature: -25 to +70 C
At the incremental inputp, the counting direction depends on the phase shift
of the two signals. The maximum frequency of a single input is 1 MHz.
If pulse channel A hurries ahead the channel B by 90 degrees (like in the
picture above), an UP-counting happens. If channel B hurries ahead the
channel A by 90 degrees, a DOWN-counting happens. This can be inverted
with MKS software.
n. c. = not connected
* = potential-free outputs, depending on mounting variation: make or
break contact: maximum switching voltage/current 24 VDC / 1 A
** = This pin is only optionally connected!
Depending on the display’s version, the voltage at this output
can also be +24 VDC!
together with Pin 3, pulse inputs (previous page),
max. current 0,5 A
The ouput voltage of Pin 2 can be used for wiring the preselection inputs.
If the wiring shall happen with an external voltage, its GND must be connected
to Pin 1.

Large Format LED Display with Pulse Counter
Procedure with BCD parallel:
Switch data signals to the display digits (HIGH-active).
Set preset input (HIGH-active).
The LE input must not be operated because it is automatically supplied with a LOW
signal if it’s not connected. In this case it is active.
Procedure with BCD multiplex:
Set an HIGH-signal to the display digits you want to use.
Set data signals for digit 100.
Activate LE 100 (= interrupt HIGH-signal or connect LOW-signal).
Repeat the last two steps for all display digits:
Das bezeichnete Produkt stimmt mit
der folgenden Europäischen Richtlinie
überein:
We herewith confirm that the above mentioned product meets the requirements of
the following standard:
Die Übereinstimmung des bezeichneten Produktes mit den Vorschriften der angewandten Richtlinie(n) wird nachgewiesen durch die Einhaltung
folgender Normen / Vorschriften:
The conformity of the product described above with
the provisions of the applied Directive(s) is demonstrated by compliance with the following standards /
regulations:
Make sure that the housing can be opened for adjustment and
maintenance even after the display has been installed. Allow for adequate clearance at the back, front and top of the display unit in order to allow for sufficient ventilation (if vent slots are included).
Display quality is impaired by direct illumination with bright light
sources and/or direct sunlight.
The display must be switched off before cleaning.
Protect the display from excessive humidity, extreme vibration, di-
rect sunlight and extreme temperatures. Non-observance may lead
to malfunctioning or destruction of the device. Under certain circumstances electrical shock, fire and explosion may occur as well.
Information concerning allowable ambient conditions, including recommended temperature ranges, can be found in the chapter entitled “Technical Data”.
The display may not be placed into service if the device and/or the
power cable are known to be damaged.
Do not attempt to repair the device yourself. The guarantee is ren-
dered null and void if the device is tampered with by unauthorised
persons.
Observe all notes and instructions included in this user’s manual.
