2. Important safeguards
1. Read these notes completely
2. Keep these operating instructions for later use
3. This unit is operated electrically with mains voltage.
Make sure to note the relevant regulations for safety and those
laid down by your national electrician’s association.
Mains voltage as well as any voltage from 42V up are highly
dangerous.
4. Before cleaning the unit, please do always disconnect it from
the mains by pulling the power plug.
5. Do not place unit on hot machine parts or in the range of
radiation of hot parts.
6. Keep power cord away from hot or sharp-edged parts.
7. Pull power plug immediately, if
- power supply cable got damaged,
- a liquid or an object got in,
- the unit got damaged by falling or any other mechanic
influence.

4. Application and installation
Temperature-controller plug-in unit complying with the
19“-rack-standard to establish multiple-zone controls.
They are inserted in the same basic-units of series Z 7530 GC
which are deliverable fully wired for 2, 4, 6, 12, 18, 24
and 30 zones.
The functional equipment of the temperature-controller
unit and its special control mode are particularly suitable
for temperature-control of hot-runner injection-moulds,
plastics and rubber machinary, extruders, presses and
tools.
High temperature stability by using a precision
control-unit with adaptive DPID-characteristics.
Careful handling of the connected heating-elements by
use of automatic startup-routine with reduced poweroutput,
feasibility of permanent power-output limitation as
well as using nearly continuous proportional zero-voltage
switching.
Very easy and concise 3-button-operation.
All operational parameters at a glance:
3-digit 7-segment LED-display indicates actual value,
control-deviation is additionally indicated on the coloured
10-segment bargraph.

5. Assembly
Small units of 2, 4 or 6 control zones are ready equipped
with temperature-controller plug-in units when delivered.
Bigger mainframes with 12 or more control-zones are
delivered separately from the controller plug-in units.
For assembly just insert the plug-in units into the spaces
provided in the mainframe.
Warning:
The mainframe must not be connected to the mains
during assembly. Please pull the power-cord!
Please turn both quick-seal coupling locks in horizontal
position and insert PC boards of the plug-in units into
lower and upper guide rail.
The front panel must engage fairly with gentle pressure.
Please press quick-seal coupling locks gently through
against spring with a screwdriver and lock with a 90°
rotation.
Do not fit the spaces designed for alarm plug-in units
with temperature controller plug-in units, there will be no

6.2 Inbetriebnahme:
Zur Inbetriebnahme der Regel-
einheit wird der Netzschalter der
Grundeinheit eingeschaltet.
Befand sich der Regler im SLEEP-
MODUS, so ist zum Einschalten
die Modus-Taste (6) länger als
4 sec. zu betätigen.
Der Regler arbeitet bei der Erst-
Inbetriebnahme mit werksseitig
voreingestellten Werten:
Temperatur-Sollwert: 100°C
Grenzwerte
- Untertemperatur: -15K
- Übertemperatur: +15K
Softstartzeit: 5 min.
Boost-Funktion: 0K (aus)
Der Temperatur-Sollwert kann
sofort geändert werden (auch
während der Softstartphase).
Alle übrigen Einstellungen sind in
der Softstartphase gesperrt.
Beim Wiedereinschalten werden
automatisch die zuletzt gefahre-
nen Werte wieder aktiviert.
Der Regler startet immer im
REGEL-/AUTOMATIK-MODUS
(normaler Betriebsmodus).
Im Display (3) erscheint die IST-
Temperatur.
6.2 Getting started:
To put the control-unit into operation
turn-on the mains-switch of the
mainframe.
If the controller-unit was in SLEEP-
MODE, press mode-button (6) longer
than 4 secs.
Factory-default control-values:
Temperature-desired value: 100°C
Limits
- process low: -15K
- process high: +15K
Softstart (time): 5 min.
Boost-funktion: 0K (off)
The desired temperature-value
may be changed immediately
(also while softstart is active).
All other parameters are locked
during softstart.
When re-starting the control-unit
all last operated parameters will
be used.
The control-unit always starts-up
in CLOSED-LOOP CONTROL-MODE
(normal operational mode).
The multi-purpose-display (3)
indicates the actual temperature.

Entsprechend der Differenz von
IST-Temperatur zu SOLL-Tempe-
ratur und entsprechend der
Vorgabe des Grenzwertes für die
Erkennung von Untertemperatur
leuchtet die Untertemperatur-
Anzeige (11) auf.
Bei Anfahrtemperaturen unter
50°C läuft automatisch die volle
Softstart-Routine ab.
Während der Softstartphase
wechseln die Dezimalpunkte im
Display (3) langsam von links
nach rechts.
Die Ausgangsleistung beträgt
anfangs 5% und wird innerhalb
der im EINRICHTER-MODUS vorge-
wählten Zeit kontinuierlich auf
ca. 60% gesteigert.
Während des Softstartes ist der
Sollwert auf 80°C begrenzt.
Auf diese Weise werden auch
massearme, flinke Heizpatronen
nach einem Kaltstart schonend
vorgewärmt und von evtl. vorhan-
dener Feuchtigkeit befreit.
Bei Anfahrtemperaturen über
50°C läuft die Softstart-Routine
verkürzt innerhalb ca. 1 min. ab.
Nach Softstartablauf vollzieht der
Regler die Streckenanalyse und
startet die volle Regelfunktion.
According to the difference between
actual and desired temperature
and according to the programmed
process-low limit the corresponding
LED (11) lights up.
At starting tool-temperatures below
50°C the complete startup-sequence
is run.
During soft-start the decimal points
slowly flash from left to righ tof the
multipurpose-display.
The initial power-output amounts
to 5% and is increased continuously
up to 60% within the time-period
programmed in setup-mode.
Softstart-temperature is limited to
80°C.
Within this routine low-mass, fast
acting heating-cardridges aregently
preheated, and moisture,which may
possibly be present, is expelled.
At starting-temperatures above
50°C the softstart-sequence is
abbreviated to 1min.
Afterwards the control-unit analyses
the controlled system and starts the
complete control-sequenze.

During the analysis of the controlled
system the decimal points quickly
flash from left to right of the multipur-
pose-display.
If the BOOST-function is active, the
programmed desired temperature will
be overstepped once to the normal
desired temperature plus the
programmed BOOST-temperature.
After that the tool is heated to the exact
desired temperature.
Depending on limit-values there might
be „process-high“-alarm during boost-
process, wheras the cooling-exit
(if established) is definitely deactivated
during boost.

flashes.
Each more tapping of ´UP´ increases
the desired value about 1°C, tapping
´DOWN` decreases about 1°C.
Continuous actuation causes fast
forward / reverse change.
New desired values can be confirmed
by pressing the mode-button, after
about 20secs the new value will be

The cooling-exit of the temperature-
controller-unit is designed to the
direct-driving of fan-motors
230V~/max.120VA.
It works narrow-band proportional
within an area of 5K, cycle-time is
10sec.
The proportional-band has a
running relation of 2K to the
process-high-limit.
Cooling exit only works if
process-high limit is > 10K.
Settings (example):
process-high limit +12K
results in proportional cooling-
function within +5K to +10K
at cooling-power 20% to 100%
+5K => 20% cooling-power
+6K => 40% cooling-power
+7K => 60% cooling-power
+8K => 80% cooling-power
+9K => 100% cooling-power
