ZIMMER PRO -V
Programmable Transducer
Installation & Operating Instructions
1. Introduction
The Zimmer PRO -V is a panel mounted 43.5X 65.5mm Transducer.
The Zimmer PRO -V is used to measure and convert AC Voltage input into an
proportional DC current or voltage output signal. Output signal generated is proportional
to the True RMS(upto 15th Harmonic) of the input Voltage.
Input Voltage and Output Voltage/Current is displayed on LCD and indicated by LED’s.

3.2 Programming of Transducer through Modbus(optional)
For programming of transducer, steps to be followed are
Step 1 : DIP Switch setting:
DIP Switches should configure for desired Output type as per given in section 3.3
Step 2 : programming
For setting Output from Current to Voltage write value “1”.
For setting Output from Voltage to Current write value “2”.
(Refer section 4.2 and table 3 parameters no. 16 & 18 for details).
The power supply must be applied to Zimmer PRO - V before it can be
programmed.
3.3 DIP Switch Setting for Output
To configure Zimmer PRO -V Output, programming method to be adapted along with
mechanical switch setting (DIP switch setting on PCB).
Type of output (current or voltage signal) has to be set by DIP switch.
1) To change O/P switches from Current to Voltage or vice versa,
ensure that transducer should be Electrically dead and all connection wires should
be disconnected.
2) Terminal screw should be tighten.
3) Remove the Back cover of transducer by using screw driver.
Insert screw driver in a snap
fitting slot and press in
direction of arrow, remove all
snap fitting pillars of back

4. RS 485 ( ModBus )
Zimmer PRO -V supports MODBUS (RS485) RTU protocol( 2-wire ).
Connection should be made using twisted pair shielded cable. All "A" and "B" connections are daisy chained
together . The screens should also be connected to the “Gnd” terminal. To avoid the possibility of loop currents,
an Earth connection should be made at one point on the network.Loop (ring) topology does not require any
termination load. Line topology may or may not require terminating loads depending on the type and length
of cable used. The impedance of the termination load should match the impedance of the cable and be at both
ends of the line. The cable should be terminated at each end with a 120 ohm (1/4 Watt min.) resistor.
RS 485 network supports maximum length of 1.2km. Including the Master, a maximum of 32 instruments can
be connected in RS485 network. The permissible address range for Zimmer PRO -V is between
1 and 247 for 32 instruments. Broadcast Mode (address 0) is not allowed.
The maximum latency time of an Zimmer PRO -V is 200ms i.e. this is the amount of time that can pass before
the first response character is output.
After sending any query through software ( of the Master) , it must allow 200 ms of time to elapse before
assuming that the Zimmer PRO -V is not going to respond. If slave does not respond within 200 ms,
Master can ignore the previous query and can issue fresh query to the slave.
The each byte in R TU mode has following format:
Exception Cases : An exception code will be generated when Zimmer PRO -V receives ModBus query
with valid parity & error check but which contains some other error ( e.g. Attempt to set floating point variable
to an invalid value ) The response generated will be “Function code” ORed with HEX (80H ).
The exception codes are listed below
01 Illegal function The function code is not supported by Zimmer PRO -V
02 Illegal Data
Address
Attempt to access an invalid address or an attempt to read
or write part of a floating point value
03 Illegal Data
Value
Attempt to set a floating point variable to an invalid value
Function code :
03 Read Holding Registers Read content of read /write location ( 4X )
04 Read input Registers Read content of read only location ( 3X )
16 Presets Multiple Registers Set the content of read / write locations ( 4X )
4.1Accessing 3 X register for reading measured values:
Two consecutive 16 bit registers represent one parameter. Refer table 2 for the addresses
of 3X registers (Parameters measured by the instruments).
Each parameter is held in the 3X registers. Modbus Code 04 is used to access all parameters.
Example :
To read parameter ,
Voltage : Start address= 00 (Hex) Number of registers = 02
Note : Number of registers = Number of parameters x 2
Each Query for reading the data must be restricted to 20 parameters or less. Exceeding the 20 parameter
limit will cause a ModBus exception code to be returned.

5.1 EMC Installation Requirements
This product has been designed to meet the certification of the EU directives
when installed to a good code of practice for EMC in industrial environments,
e.g.
1. Screened output and low signal input leads or have provision for fitting
RF suppression components, such as ferrite absorbers, line filters etc., in
the event that RF fields cause problems.
Note: It is good practice to install sensitive electronic instruments that are
performing critical functions, in EMC enclosures that protect against electrical
interference which could cause a disturbance in function.
2. Avoid routing leads alongside cables and products that are, or could be, a
source of interference.
4. ESD precautions must be taken at all times when handling this product.
3. To protect the product against permanent damage, surge transients must
be limited to 2kV pk. It is good EMC practice to suppress differential
surges to 2kV at the source. The unit has been designed to automatically
recover in the event of a high level of transients. In extreme
circumstances it may be necessary to temporarily disconnect the
auxiliary supply for a period of greater than 5 seconds to restore correct
operation.
The Current inputs of these products are designed for connection in to
systems via Current Transformers only, where one side is grounded.
5.2 Case Dimension and Panel Cut Out
5.3 Wiring
Input connections are made directly to screw-type terminals with indirect
wire pressure. Choice of cable should meet local regulations. Terminal for both
Current and Voltage inputs will accept up to 2x 2.5mm² or 1x6mm² cables.
5.4 Auxiliary Supply
Zimmer PRO - V should ideally be powered from a dedicated supply, however it
may be powered from the signal source, provided the source remains within
the limits of the chosen auxiliary voltage.
5.5 Fusing
It is recommended that all voltage lines are fitted with 1 amp HRC fuses.
5.6 Earth/Ground Connections
For safety reasons, CT secondary connections should be grounded in
accordance with local regulations.
Table 4 : RS 485 Set-up Code
Note :
Codes not listed in the table above may give rise to unpredictable results including loss of
communication. Exercise caution when attempting to change mode via direct Modbus writes.

Caution
1. In the interest of safety and functionality this product must be installed by
a qualified engineer, abiding by any local regulations.
2. Voltages dangerous to human life are present at some of the terminal
connections of this unit. Ensure that all supplies are de-energised before
attempting any connection or disconnection.
3. These products do not have internal fuses therefore external fuses must
be used to ensure safety under fault conditions.
As the front of the enclosure conforms to IP 40 it is protected from water spray
from all directions, additional protection to the panel may be obtained by the
use of an optional panel gasket. The terminals of the product should be
protected from liquids.
The Zimmer PRO - V should be mounted in a reasonably stable ambient
temperature and where the operating temperature is within the range
0
-10 to 55 C . Vibration should be kept to a minimum and the product should
not be mounted where it will be subjected to excessive direct sunlight.
The Zimmer PRO - V can be mounted either on a top-hat rail or directly on to a
wall or a mounting plate.
