Counter / batch controller 2061 for pulse sensors
Description
Counter 2061 suits well for distance measurement
of various movement sensors, for piece count or for
dosage. Counter has red or green display, count
up or down. Input pulse can be scaled to correspond
desired number value, f.ex.one pulse may corre-
spond three numbers or parts of numbers in display
(1 pulse=0.034 digits in display).
Display memory stores calculated value for one
week after power break.
You can use counter as a dosimeter by setting
alarm value to correspond desired batch value.
Output relay is activated when calculated batch is
reached. New count starts by resetting counter with
a remote contact. You can also determine start
level from which you count down (emptying) or up
(filling).
Output relays can also be used as an pulse divider
when using internal reset (Loop function). When alarm
value is reached, f.ex. 26,5 input pulses are converted
to correrspond one output pulse; in this state output
relay sends only 200 mS impulse when counter resets.
Count amount can be set with front panel arrow keys.
Input cards of this meter belongs to a 2000 product
series and chancing the input card to another type
changes the whole meters functions. F.ex. counter for
analog input signal is available as model 2026 (own
data sheet). Whole 2000 series is based on red or
green display motherboards (also available low and
high voltage power supply) which combines 36 variants
of digital panel meter. With optional add-on cards you
can modify a meter that suits best for your application.

Serial output RS485/RS232 (option)
Meter may be provided with optional serial output and
you can read measurements by e.g. PC. Display
programming can not be made via serial port. Addi-
tional card provides serial signal RS232 and RS485,
only one of those can be selected.
Serial signal is isolated from both input signal and
power supply. Meters with RS485 can be max. 31 in
same loop and longest distance 1000m. RS232 en-
ables only connection of two devices and max. dis-
tance 10..20 m.
In programming stage you can first select card type
(serial) mounted to slot B or C and then address and
Baud rate. Baud rates are: 300, 1200, 2400, 4800,
9600, 19200 and addresses 0...127.
Accept selection and move forward by -key. You
come back to previous level always by -key.
Program remembers card type mounted, if ithas been
saved by save command when leaving program. In
case you can not choose serial card, slot has
automatically recognized card (plug and play).
Terminal connections:
By serial signal RS485 last unit must be
terminated by 110 ohm resistor. you can
make termination at terminal connectors
or by connecting jumper J1 to ON-
position.

Serial protocol (SCL):
MESSAGES: When asking the measurement data
from the panelmeter 2061 through the serial port, a
command sequence which is in accordance with the
SCL protocol is used for the inquiry:
(Only the measurement results can be asked from the
panelmeter 2061)
<ADDR+80h>COMMAND STRING<ETX><BCC>
<ADDR>
The first byte character to be sent contains the ADDR
(0..127) of the address of the destination device and at
the same time functions as the start bit of the com-
mand. 80H (in a decimal 128) with which an uppermost
bit is set as the number one is added to the address.
COMMAND STRING: When measurement data is
requested, the actual command is: MEA CH 1 ? , in
which 1 means the channel number. (there is only one
channel in the panelmeter 2061 so the number is
always 1).
<ETX>
<ETX> mean the end mark of the command,
ASCII character 03h.
<BCC>
Finally the checksum is calculated using the XOR
operation on the byte characters of the actual com-
mand including the ETX. In the example the ASCII
codes have been presented in hexadecimal.
e.g.
One wants the measurement result from the display
unit address 1. To the channel an inquiry is sent:
MEA CH 1 ? (ASCII codes shown for <BCC>
calculation)
M E A C H 1 ?<ETX> <BCC>
4Dx45x41x20x43x48x20x31x20x3F x03 = 6F
(Presented the XOR operation with a character x)
(ASCII code 20h corresponds to space character)
So the following bytes are sent to 2061:
81 4D 45 41 20 43 48 20 31 20 3F 03 6F
RETURN MESSAGE: The answer from the panelmeter
2061 is obtained in the following format:
<ACK>RETURN MESSAGE<ETX><BCC>
<ACK>
The first byte of the answer contains the start of the
answer <ACK> (ASCII-code 06h) and the answer
itself, endmark <ETX> (ASCII- 03h) and the checksum
of the answer which is calculated from all the byte
characters of the answer including <ACK> and <ETX>.
2061 counts the checksum in which case the receiver
does not need necessarily to care about it,
e.g.
e.g. When a measurement result is for example 21.3,
it will be obtained from the panelmeter in the following
form
<ACK> 2 1 . 3 <ETX> <BCC>
Answer: 06 32 31 2E 33 03 1B

The 2000 series panelmeters are modular and easy to
assemble. According to customers wishes. The basic
construction consists of mother board with tree slots,
A, B and C. Slot A determines meter type and provides
always input signal. Slot B and C are interchangeable.
As factory delivery input signal is always installed into
slot A , mA output into slot B and alarms into slot C. In
case of f.ex 4 alarms and relay card with 2 change-over
contact (2 + 2 relays) are used, you must place second
Slots A-C
Change of meter
type:
Input card is placed always
to slot A. By changing input
card you can get an other
type of meter. You can
change meter with pulse
input to meter with current
input, thermocouple, strain
gage etc.
Additional slots:
Additional cards provide
output 4..20 mA, alarms,
serial interface, BCD output
etc. Meter data sheet
dictates possible combina-
tions. grey connectors allow
line voltage 110..240 VAC
(relay contacts).
Power supply:
There are two different mother
boards power supply 85..240
VAC and 12..32 VDC. VDC-
mother board accepts
24 VAC. Connectors are
colour coded.
relay card into slot B. If you accept only closing or
opening relay contacts, you need only one relay card
with 4 relays placed into slot C. The slot B is now
usable for other optional outputs.
You can have different types of meters by only
changing the input card in slot A. Data sheet of each
type of meter dictates the possible combinations.
Recalibration of card is not needed; only scaling and
other settings must be set by front panel keys.
All cards have calibration
memory
Press gently case behind front panel
and draw frame outwards gripping

remove mother board from rear by
opening four screws in corners of case.
