Panel mounting:
To fix the unit, insert the brackets provided into the seats on either side of the
case. To mount two or more units side by side, respect the cut-out dimensions
shown in the drawing.
CE MARKING: EMC conformity (electromagnetic compatibility) with EEC Directive
89/336/CEE with reference to the generic Standard EN50082-2 (immunity in industrial
environments) and EN50081-1 (emission in residential environments). BT (low voltage)
conformity respecting the Directive 73/23/CEE modified by the Directive 93/68.
MAINTENANCE: Repairs must be done only by trained and specialized personnel. Cut
power to the device before accessing internal parts.
Do not clean the case with hydrocarbon-based solvents (Petrol, Trichlorethylene, etc.).
Use of these solvents can reduce the mechanical reliability of the device. Use a cloth
dampened in ethyl alcohol or water to clean the external plastic case.
SERVICE: GEFRAN has a service department. The warranty excludes defects caused
by any use not conforming to these instructions.

  • Page 1 Digital communication wire 0,35 mm 3,5 m SERVICE: GEFRAN has a service department. The warranty excludes defects caused C.T. connection cable 1,5 mm 3,5 m by any use not conforming to these instructions.
  • Page 2 3 and no. 5 1.5) Outputs: Type 600 controllers have up to 4 outputs, depending on the model. Each output can be mapped via software to perform one or more functions. It is for example possible to assign a combination of alarms to one output relay. It is also possible to assign the main control function to any of the outputs.

  • Page 3: Programming And Configuration

    On the 600-R-?-C-?-? the analog output can only be used for control purposes. The 600-R-?-W-?-? can be configured for analog control or for analog retransmission. Change from 0-20 (0-10V) to 4-20mA (2-10V): This is a software setting. In the "Out" menu set rL.3=64 heat) or 65 (cool) for control purposes. For retransmission go into the "U.CAL"...

    2) Configuration menus: 2.1) Description of menus: The programming of the 600 controller is divided into 10 menus: INF: the information menu contains general information (software version etc.) CFG: the configuration menu contains all parameters affecting the control behavior (enabling of self-/autotune, PID parameters, hysteresis, softstart time, loop break power etc.)

    "rL.2" sets the function of out2 (terminals 19 + 20). Normally rL.2=0, (main output for heating) "rL.3" sets the function of out3 (terminals 5 + 6). It only applies to units with a third output.

  • Page 17: Decimal Point

    Changing the input scale also affects the proportional band in PID control because h.Pb and c.Pb are a % of the input range. • Standard Sensor The Gefran 600 controller allows changing of the sensor scale. For standard temperature sensors (thermocouples, Pt100…) the Lo.S and Hi.s parameters should normally correspond with the minimum and maximum temperature scale of the particular sensor, as listed in the input table.

  • Page 19 For combined heat/cool control two outputs will be occupied. Hence you need a controller with more than two outputs (e.g. 600-R-D-R-0-1) if you want heat/cool control with alarm. If you use a controller with only two outputs for heat/cool control (e.g 600-R-R-0-0-1), no spare output for alarm is available, hence the alarm should be disabled by setting Al.n=0 It is possible to enable up to 3 alarms.

  • Page 20: Manual Mode

    15 • HEAT BREAK ALARM (AUX. INPUT 2) controllers with input/output 3 option ="H" monitor the load current via a 50mA secondary current transformer (refer to Gefran CT type 330200 and 330201). The load current can be displayed via the bottom SV display (set dSP=1 in Hrd menu). The scaling of the input is achieved by setting LS.2 (normally LS2=0) and HS.2 in the InP menu.

  • Page 21: Display Functions

    17 • DISPLAY FUNCTIONS • SV Display (bottom display) The function of this display can be configured by setting the dSP parameter in the Hrd menu. Normally dSP=0, showing the control setpoint. However the display can also be configured to display the value of the auxiliary input, the output power or the deviation of the process variable from the setpoint.
  • Page 22 • Selftune Selftune is performed on a cold process (power-up) and is a once-off process. At power-up the controller will provide full power for a brief moment, then monitor rise and fall of the process variable, calculate the PID parameters and the revert to normal control. It is useful to configure one of the three LEDs L1, L2 or L3 to indicate or flash while autotuning is active.
