Electrical Connection

Attention!
Observe terminal assignments at the housing front panel!
The instrument is not equipped with an integrated circuit breaker.
Therefore, during installation, care should be taken to ensure that
– the building where the instrument is installed includes a circuit breaker,
– the circuit breaker is positioned in close proximity to the instrument and is easily accessible to the operator
– it is clearly marked as a circuit breaking device for the instrument.
Tighten screws with a manual screwdriver only!
Maximum tightening torque for all screw connections is 0.6 Nm.
Connectors: Terminal blocks for wires with cross-sections of up to 2.5 square mm, or two-core wire-end ferrules for cross-sections of up to 2 x 1.0 square mm
EN 55022 requires the following warning as regards electromagnetic compatibility:
Warning
This is a class A device. It may cause radio interference in residential environments.
If this is the case, the operator may be required to implement appropriate corrective measures.
Reliable wiring is accomplished with the help of screw and clamp-type terminals which are separated according to function. Only terminal blocks of like polarity or identical color may be plugged onto the appropriate bases.
Mismatching of the terminal blocks may result in damage to the R6000 controller or interconnected components.
4.1 Terminal Assignments  4.2 Auxiliary Voltage
Auxiliary voltage is 24 V DC.
The two connector terminals for the negative poles are connected with one another inside the device, as is also the case for the two positive poles.
In this way, supply power can be looped through to several R6000 controllers. The terminals have a maximum current carrying capacity of 10 A (also in the event of malfunction) which may not be exceeded!
The terminal block for auxiliary voltage is black.
A completely separate safety power supply system is to be used for operation of the instrument.
4.3 Binary Inputs / Outputs (I/O)

Figure 6 Schematic Diagram, Binary Inputs / Outputs
Binary I/Os which are configured as outputs connect the auxiliary voltage positive pole by means of a semiconductor switch. The load (SSR, controller input etc.) is connected to the auxiliary voltage negative pole. Three SSRs can be connected in series for controlling 3-phase heaters.
Maximum load for each individual output is 500 mA, with a limit of 3 A per controller. All outputs are safeguarded by means of integrated, self-restoring overload protection.
Attention!
After overload protection has been triggered, not only does the overload have to be eliminated, all other outputs must be de-energized as well in order to allow for self-restoration of the circuit breaker. Self-restoration may take several minutes.
If the I/Os are used as inputs, control is accomplished either by means of an active positive signal at the auxiliary voltage negative pole, or with a floating contact which switches the auxiliary voltage positive pole to the input.
The assignment of I/Os to channels and functions can be freely configured via the interface.
Attention!
Before I/Os used as inputs are configured as such, an active output signal can be read out depending upon configuration.
The output of the connected device may thus be damaged as a result.
4.4 Thermocouple and Pt100 Measurement Inputs (sensors 1 through 8)Figure 7 Sensor Terminal Assignments
Thermocouples are connected to the positive and negative terminals.
No connections may be made to the ⊥ terminal.
If impermissible measured values should occur when using insulated thermocouples, all negative legs at the insulated thermocouples should be connected to each other. If necessary, they can be connected to the switch cabinet ground terminal.
3-wire connection is used for Pt100 sensors.
In the event of 2-wire connection, the negative terminal must be connected to the ⊥ terminal at the controller.
The ⊥ terminals are connected with each other internally.
If Pt100 sensors with 4-wire connection are used, the fourth wire may not be connected at all.
The reference junction (CJ) remains attached also for PT100 sensors.
4.5 Remote Cold Junction (CJ)

Figure 8 Schematic Diagram, Remote Cold Junction
If the thermocouple equalizing leads are not connected to the controller, the Z306A accessory (remote cold junction) is required. The remote cold junction includes a temperature sensor and a 2-pole terminal block.
The plug-on reference junction (CJ) at the R6000 is removed and is replaced with the 2-pole terminal block. The temperature sensor is attached at the transition from the thermocouple or the equalizing lead to the copper conductor, and is connected to the 2-pole terminal block at the R6000.
The original reference junction which has now been removed from the R6000 is not used.
4.6 Additional Binary Inputs / Outputs (I/O)
Device variants including feature A1 have four additional I/Os.
All of the specifications included in chapter 4.3 on page 9 apply to these I/Os as well.
No connections may be made at the AO negative terminals at the same terminal block.
4.7 Heating Current Monitoring (HC 1 … 3, HV)Figure 9 Schematic Diagram, Current Transformer Connection
Commercially available current transformers with max. 1 A secondary current are connected to terminals HC k and l. Compliance voltage is max. 2 V.
Three inputs are provided for monitoring 3-phase current.
Several control loops are monitored via summation current principle.
Attention!
If the terminal block is removed during operation, excessive voltage occurs at the secondary side of the current transformer.
In order to enable more accurate current monitoring, current fluctuations which result from line voltage fluctuations can be compensated. A voltage transformer with a secondary open-circuit voltage of 12 to 40 V is connected to terminals HV u and v to this end. A representative phase voltage from the heater power supply is used at the primary side. All interconnected transformers must assure safe electrical separation, and may not be connected to each other at the secondary side.
4.8 Data Interfaces

4.8.1 RS 232 Service Interface
9-pin sub-miniature plug connector at the controllerFigure 10 Diagram of Sub-miniature Plug for RS 232 Interface

A non-crossed serial extension cable (modem cable) is required for connection to a laptop or a notebook. This can be ordered as an accessory (article no. GTZ 3241000R0001).
With the CAN bus and Profibus variants (features F1 and F2), the service interface can be used independent of bus operation.
Attention!
With RS 485 variants (features F3, F4), communication is only possible via the service interface after the 4-pole bus plug has been removed, or when the bus is not in use.
4.8.2 Bus Interfaces
The following points must be observed when wiring the bus interfaces:
– Corresponding terminals must all be connected in parallel.
– Wiring must be executed from device to device, devices may not be star-connected.
– The two bus ends should be terminated with characteristic wave impedance.
This is accomplished by setting the “R” switch at the R6000 to “on”.

6.2 Device Performance after Connecting Auxiliary Voltage

• As soon as auxiliary voltage is connected, the green “Power” LED lights up.
• Shortly thereafter, the green “Run” LED lights up, and the red “Error” LED blinks once briefly.
• The binary output LEDs then light up in accordance with control loop settings. The binary output LEDs may light up even if auxiliary voltage has not been connected, if the inputs are driven actively.
• The yellow LED for the respective bus terminal indicates active bus communication.

6.3 Possible Errors

Parameters Configuration and Operation

Information regarding parameters configuration and operation of the R6000 is included in the comprehensive operating instructions.
These are available from the internet at www.gossenmetrawatt.de.
Read the operating instructions completely and carefully before using the device, and follow all instructions included therein.
The operating instructions should be made available to all users.

Maintenance and Service

The R6000 controller does not require maintenance at regular intervals.
If the controller should nevertheless require replacement, it can be removed from the rail by pulling on the tab at the bottom of the device.
This disengages the top-hat rail mount and the controller can be removed by lifting it up and forward.
Before replacement, the DIP switches at the replacement device must be configured to match those at the original device (bus address and selection of Pt100 or thermocouple).
The replacement device is attached to the top-hat rail with the mounting hooks at the rear, and is snapped into place by gently pushing down and back.
Screw or clamp-type terminal blocks can plugged from one device to the next for quick device replacement if service is required.
