Short Operating Instruction
for temperature regulator 400
We deliver our temperature regulator in its basic adjustment for the control of heaters. For other applications, the
parameters should be accordingly modified with the help of the attached operating instruction.
1. Link: There is a link for the thermocouple (NiCr Ni, type K) on the front plate. Laterally, heaters can be
steered through the automatic controller. The permissible power for each power connection amounts to 5 A
with 230 ~V. Attention the output is only for resistive load!
2. Display: The temperature (actual value) measured at the thermocouple is displayed. Heater switching
impulses (220 V at the plug sockets) are displayed by a red LED down/up OUT 2. If the actual value is
below the set point, this is displayed by a red LED arrow directing to the left (LOW); if the actual value
exceeds the set point, this is indicated by a red LED arrow directing right (HIGH) OUT 2 turn off; no 220 V
at the plug sockets). If the actual value is within the range of tolerance of the set point, a green beam-LED
lights up.
3. Temperature adjustment: Through pressing key >F< on the front plate „-SP“ appears, alternating with the
set point actually given. With the arrow keys > v/ ^< the desired set point can be set. After the
modification press key >F< again to transfer the new set point (display: > AL.1<). After 5 seconds the
instrument switches back into the initial state and the modified set point is taken over. If the desired value is
modified and there is no acknowledgement by key >F< after 5 seconds, the instrument again switches back
into the initial state, but the set point is reduced to the lower alarm value. By pressing key >F< second time
(next of the set point), further values such as alarm value 1 and 2 (optionally) and the placing degrees (not
by automatic, only by manual) can be called up. Note: if key >F< is initially pressed longer than 2 seconds,
you achieve a level on which there is the danger of an unintentional change of the functional parameters.
4. Temperature control: Thermocouple NiCr Ni type K, without self-optimization and auto optimization,
proportional temperature control, with soft start function (note: heating regulates the full heating power after
approximately 3-5 minutes; in any case soft start for the protection of the heating cartridge).
Important adjustments for modifications of the temperature control:
Blocked: Pass: 99 (protection: 28)
by parameter CFG (press >F< key for 2 seconds, press twice afterwards, CFG appears)
S.tu: Adjustment whether working with optimization (see instruction)
h.Pb: Value of heating in proportion to the final value of the thermocouple; i.e. the regulation starts 1 % of
the thermocouple’s final value below the set point. Example: adjustment: 1,0, thermocouple type K: 1300°C
= 1 % = 13 °C, set point: 500 °C; this means that the temperature control is started at 487°C.
h.It: the smaller the value, the more an adaptation value to the set point is attempted. If the value is small,
there is the danger of over swing.
h.dt: the larger the value, the more an over swing is prevented; this affects a dampening of the controlling
action. The relation of the values h.It to h.dt should always be 4:1.
5. Manual regulation: Through pressing key > O< you can choose between automatic and manual operation.
In case of manual operation the instrument is only used as a momentum generator and there is no need for a
thermocouple (important when sensor breaks). After reversing, all LED light up and the position can be
chosen. Value 100 means constant heating, value 50 means that the processes of turning on and turning off
take equally long. The clock speed is entered. A set point is not considered. The temperature and the set
value are displayed alternately. Change over to the automatic mode by pressing key > O<.
6. Turning on/Turning off: The instrument can be turned on and off by plucking in the power supply plug or
pulling it off. Furthermore, there is the possibility of turning the instrument off while it is connected with the
voltage supply. Therefore, key >F< and key > ^< have to be pressed at the same time and for 5 seconds.
After turning the instrument off, only a decimal point can be seen. The instrument is turned on by pressing
key >F< for 5 seconds.
7. Alarm outputs: Optionally the instrument can also be delivered with a socket for alarm outputs. The contact
is closed by alarm (alarm 1, 2 and sensor breaks).
8. A fuse is installed inside as protection, if the current is more than 5 amperes. Attention: The relay can
switch only resistive load (ohm-resistance)! Don’t regulate transformer and systems with more as 5
amperes. Working temperature: -10 to +40°C
We recommend the adjustment with auto- and self-optimization respectively; for further information please see
attached instruction.

This type of alarm is conditioned by use of the current transformer input. (T.A.)
It signals variations of load absorption by discriminating the level of current at the transformer input in the range (0...HI.A). It is
enabled with configuration code (AL.n); in this case the alarm trip value is expressed in HB scale points.
Select the type of functioning and the assigned control output by means of code Hb.F (“Out”phase).
The alarm limit setting is A.Hb.
The direct HB alarm trips if the value of the current transformer input is below the set limit for Hb.t seconds inclusive of “ON”
time of the selected output.
The HB alarm can be activated only with ON times longer than 0.4 seconds.
HB alarm function also includes control of load current in the OFF interval of the cycle time for the selected output: the HB
alarm will trip if the measured current exceeds approximately 12.5% of the full scale set (parameter HI.A in InP) for Hb.t
seconds inclusive of the OFF state of the output.
The alarm is reset automatically if the cause of the alarm is eliminated.
Setting a limit of A.Hb = 0 disables both types of HB alarms, with de-energizing of the assigned relay.
Indication of load current is displayed by selecting term C.T. (level 1).
NOTE: ON/OFF times refer to the cycle time set for the selected output.
Alarm Hb_F = 3 (7) continuous is active for a load current value below the set limit; it is disabled if the value of the
heating(cooling) output is less than 2%.

These transformers are used to measure currents of 50 ÷60Hz from 25A to 600A
(nominal primary current). The peculiar characteristic of these transformers is the high
number of secondary turns. This provides a very low secondary current, suitable for an
electronic measurement circuit. The secondary current may be detected as voltage on a
resistor.

•WARNINGS
Read the following warnings before installing, connecting or using the device:
•follow instructions precisely when connecting the device.
•always use cables that are suitable for the voltage and current levels indicated in the technical specifications.
•the device has no ON/OFF switch: it switches on immediately when power is turned on. For safety reasons, devices permanently connected to the power
supply require a two-phase disconnecting switch with proper marking. Such switch must be located near the device and must be easily reachable by the
user. A single switch can control several units.
•if the device is connected to electrically NON-ISOLATED equipment (e.g. thermocouples), a grounding wire must be applied to assure that this
connection is not made directly through the machine structure.
•if the device is used in applications where there is risk of injury to persons and/or damage to machines or materials, it MUST be used with auxiliary alarm
units. You should be able to check the correct operation of such units during normal operation of the device.
•before using the device, the user must check that all device parameters are correctly set in order to avoid injury to persons and/or damage to property.
•the device must NOT be used in inflammable or explosive environments. It may be connected to units operating in such environments only by means of
suitable interfaces in conformity to local safety regulations.
•the device contains components that are sensitive to static electrical discharges. Therefore, take appropriate precautions when handling electronic circuit
boards in order to prevent permanent damage to these components.
Installation: installation category II, pollution level 2, double isolation
•power supply lines must be separated from device input and output lines; always check that the supply voltage matches the voltage indicated on the
device label.
•install the instrumentation separately from the relays and power switching devices
•do not install high-power remote switches, contactors, relays, thyristor power units (particularly if “phase angle”type), motors, etc... in the same cabinet.
•avoid dust, humidity, corrosive gases and heat sources.
•do not close the ventilation holes; working temperature must be in the range of 0...50°C.
If the device has faston terminals, they must be protected and isolated; if the device has screw terminals, wires should be attached at least in pairs.
•Power: supplied from a disconnecting switch with fuse for the device section; path of wires from switch to devices should be as straight as possible; the
same supply should not be used to power relays, contactors, solenoid valves, etc.; if the voltage waveform is strongly distorted by thyristor switching units
or by electric motors, it is recommended that an isolation transformer be used only for the devices, connecting the screen to ground; it is important for the
electrical system to have a good ground connection; voltage between neutral and ground must not exceed 1V and resistance must be less than 6Ohm; if
the supply voltage is highly variable, use a voltage stabilizer for the device; use line filters in the vicinity of high frequency generators or arc welders;
power supply lines must be separated from device input and output lines; always check that the supply voltage matches the voltage indicated on the
device label.
•Input and output connections: external connected circuits must have double insulation; to connect analog inputs (TC, RTD) you have to: physically
separate input wiring from power supply wiring, from output wiring, and from power connections; use twisted and screened cables, with screen connected
to ground at only one point; to connect adjustment and alarm outputs (contactors, solenoid valves, motors, fans, etc.), install RC groups (resistor and
capacitor in series) in parallel with inductive loads that work in AC (Note: all capacitors must conform to VDE standards (class x2) and support at least 220
VAC. Resistors must be at least 2W); fit a 1N4007 diode in parallel with the coil of inductive loads that operate in DC.
GEFRAN spa will not be held liable for any injury to persons and/or damage to property deriving from tampering, from any incorrect or
erroneous use, or from any use not conforming to the device specifications.
!WARNING: this symbol indicates danger.
It is seen near the power supply circuit and near high-voltage relay contacts.

Proportional Action:
action in which contribution to output is proportional to deviation at input (deviation = difference between controlled variable and setpoint).
Derivative Action:
action in which contribution to output is proportional to rate of variation input deviation.
Integral Action:
action in which contribution to output is proportional to integral of time of input deviation.
Influence of Proportional, Derivative and Integral actions on response of process under control
* An increase in P.B. reduces oscillations but increases deviation.
* A reduction in P.B. reduces the deviation but provokes oscillations of the controlled variable (the system tends to be unstable if P.B. value is
too low).
* An increase in Derivative Action corresponds to an increase in Derivative Time, reduces deviation and prevents oscillation up to a critical
value of Derivative Time, beyond which deviation increases and prolonged oscillations occur.
* An increase in Integral Action corresponds to a reduction in Integral Time, and tends to eliminate deviation between the controlled variable
and the setpoint when the system is running at rated speed.
If the Integral Time value is too long (Weak integral action), deviation between the controlled variable and the setpoint may persist.
Contact GEFRAN for more information on control actions.
•CONTROL ACTIONS
•MANUAL TUNING
A) Enter the setpoint at its working value.
B) Set the proportional band at 0.1% (with on-off type setting).
C) Switch to automatic and observe the behavior of the variable. It will be similar to that in the figure:
D) The PID parameters are calculated s follows: Proportional band
Peak
P.B.= ---------------------------------------- x 100
(V max - V min)
(V max - V min) is the scale range.
Integral time: It = 1.5 x T
Derivative time: dt = It/4
E) Switch the unit to manual, set the calculated parameters. Return to PID action by setting
the appropriate relay output cycle time, and switch back to Automatic.
F) If possible, to optimize parameters, change the setpoint and check temporary response.
If an oscillation persists, increase the proportional band. If the response is too slow, reduce
it.

The function works for single output systems (heating or cooling). The self-tuning action calculates optimum control parameter values during
process startup. The variable (for example, temperature) must be that assumed at zero power (room temperature).
The controller supplies maximum power until an intermediate value between starting value and setpoint is reached, after which it zeros power.
PID parameters are calculated by measuring overshoot and the time needed to reach peak. When calculations are finished, the system
disables automatically and the control proceeds until the setpoint is reached.
How to activate self-tuning:
A. Activation at power-on
1. Set the setpoint to the required value
2. Enable selftuning by setting the Stun parameter to 2 (CFG menu)
3. Turn off the instrument
4. Make sure the temperature is near room temperature
5. Turn on the instrument again
)
.
.)
The procedure runs automatically until finished, when the new PID parameters are stored: proportional band, integral and derivative times
calculated for the active action (heating or cooling).
.
When finished, the Stun code is automatically cancelled.
Notes :
-The procedure does not start if the temperature is higher than the setpoint (heating control mode) or if the temperature is lower than the
setpoint (cooling control mode). In this case , the Stu code is not cancelled.

•AUTO-TUNING
Enabling the auto-tuning function blocks the PID parameter settings.
It can be one of two types: permanent (continuous) or single-action
(one-shot).
* Continuous auto-tuning is activated via the Stu parameter (values 1,
3, 5). It continuously reads system oscillations, immediately seeking
the PID parameter values that reduce the current oscillation. It does
not engage if the oscillations drop below 1.0% of the proportional
band. It is interrupted if the set-point is changed, and automatically
resumes with a constant set-point. The calculated parameters are not
saved if the instrument is switched off, if the instrument is switched to
manual, or if the configuration code is disabled. The controller
resumes with the parameters programmed before auto-tuning was
enabled.
p .
* One-shot auto-tuning can be enabled manually or automatically. It is
activated via the Stu parameter (as can be seen on the table, the
values to be set depend on whether Self-tuning or Soft-start is
enabled.). It is useful for calculation of PID parameters when the
system is around the set-point. It produces a variation on the control
output at a maximum of ± 100% of the current control power limited by
h.PH - h.PL (hot), c.PH - c.PL (cold), and assesses the effects in timed
overshoot. The calculated parameters are saved.
