AP11-37 Counter is 5 digit programmable panel meter for measuring in time dependent current signal.De-
vice is controlled with digital signal processor with A/D transducer.Counter is operated with key-board pla-
ced on front panel or with control software that is used for setting of all parameters and archiving measu-
red values. Panel meter has tobe provided with communication line, variants of communication lines are in
ordering code. Control software is included in standard delivery. Counter is equipped with three-colour dis-
play allowing for a quick check of limits within measured value oscillates. Visually interesting element is au-
xiliary horizontal bargraph. AP11 Counter inputs are assembled for unified outputs from sensors of techno-
logical processes
(0/4-20 mA, 0/2-10 V).There is an variant with analogue output that can be galvanic separated in panel me-
ter ordering code.With multi-stage types of panel meters analogue output can be assigned to any input by a
program, eventually to sum. Any of the communication line variants can be used for communication of panel
meter with PC.Communication lines RS232 or RS485 (can be galvanic separated) are in ordering code. Com-
bination of two communication lines RS232 and RS485 can be used for above standard applications. Com-
munication enables not only setting of parameters and data archiving, but regarding the possibility of ad-
dressing of individual panel meters it can be also used for interconnection of bigger number of panel me-
ters and controlling of complete technological lines.

Key „SET“ is used for setting data, programming termination, data uploading into EEPROM and return to
operating mode.
6 - Key „DOWN“
Key „DOWN“ is used for browsing parameters and setting of numeric data when programming. Pushing and
keeping down of the key speeds up browsing and setting procedure.
5 - Key „UP“

3 - Bargraph
Bargraph relates to measured value that is determined with pre-set range of STR and END.
E.g. if start of range (STR) is 0 and end (END) 200 and measured value shall be on level 100, bargraph shall in-
dicate half of the scale. Bargraphs is formed with column of LED diodes.

CONNECTION
4.2.1
Fix panel meter into panel with two clamps (included in delivery).
Connect conductors into screw connectors on the back panel of regulator. Connectors are designed as
separately detachable constructions blocks as follows:
connectors 11 to 18 – process and pulse inputs
connectors 21 to 28 – analogue output
connectors 31 to 38 - communication
connectors 41 to 46 – relay output
connectors 51 to 56 - relay output
connectors 61 to 63 – power supply
Pull each block with connectors out from panel meter (locking force has to be surpassed) in backward di-
rection.Then connect conductors to released blocks with connectors and then insert blocks back to appa-
ratus.
Max. cross section of conductors on relay connectors and power supply is 2,5 mm2, on other connectors
1 mm2.

Description of back panel
Instructions for installation into panel and connecting 4.2
Following rules should be observed with designing of the system:
a) All power supply conductors and power lines has to be led separately from signal lines
(e.g. thermocouple, communication). Min. gap between these types of lines shouldn´t be less than 30 cm.
b) If signal line crosses power line they should intersect in right angle.
c) Lead the lines out of the potential source of interference.
d) Don‘t install relay and contactors too close to panel meter.
e) Use twisted and screened conductor for signal line.

Danger: Don‘t connect panel meter to power supply until all inputs are connected. Wrong connection
of panel meter can cause injury!
Panel meter connection
During connecting of panel meter main switch or safety circuit breaker has to be:
- part of building installation
- in the close vicinity of equipment
- easy to reach for operating personnel
- marked as equipment disconnecting element
If the equipment is used in different manner than specified by producer, protection provided with
equipment can be disturbed.

If LED diode IN 1 flashes panel meter needs to be recalibrated.
Unplug panel meter from power supply. Keep key SET pressed and connect the panel meter to power sup-
