1. Description of the device
General description
The high press re calibrator enables
press re to be generated by means of
the integrated press re p mp, p to
700 bar relative.
The meas rement technology incor-
porated into this device allows ac-
c rate meas rement and doc men-
tation of the characteristic of a test
object that is connected to it. The
meas red press re progression can
be displayed, eval ated and saved
with a comp ter monitoring program
(CCS30).
The calibrator is operated with the
two f nction b ttons SELECT and
ENTER, located directly below
the display. The calibrator itself is
powered by a 3,0 V battery.
Copyright
For copyright reaons this operating
man al may only be sed for inho se
p rposes.
Any reprod ction, even in part and for
inho se p rposes, req ires the assent
by Messrs
Also, any distrib tion to third parties is
prohibited for competitive reasons.
Commissioning
A press re-resistant connection for
the test object is req ired in order to
se the high press re calibrator. The
press re connection for the test object
is already screwed to the press re
distrib tor of the high press re calibra-
tor so that it is press re resistant when
it leaves the factory, and it m st not be
dismantled.
Recommended torq e for the test
object press re connection: 30 Nm
IMPORTANT!
Nothing m st adhere to the s rface of
the test object (no oil, grease, water,
etc). Imp rities co ld pass tro gh the
adapter to reach the high press re
calibrator and damage it.
Overpress re
If the press re exceeds the meas ring
range by more than 20%, the meas r-
ing cell or the mechanism of the high
press re calibrator may be destroyed
Recalibration
The recalibration cycle depends on
the conditions of se. Recommended
recalibration cycle: 1 year.
Intended se
The high press re calibrator may
only be sed to generate press re
with the type HLP 22 BP hydra lic oil
that is s pplied with the prod ct. Use
of the calibrator with other media will
damage it. The operational safety
of the device s pplied is g aranteed
only if it is sed as intended. The limit
val es as stated (see page 9: ”Tech-
nical data”) m st never be exceeded.
Before installing the high press re
calibrator, check that it is s itable for
yo r applications
2. General safety warnings
The c rrent national reg lations on
accident prevention and
workplacesafety m st be followed
whenever work is carried o t.
Internal reg lations iss ed by the
operator m st
be followed, even if
they are not mentioned in these
instr ctions.
Never se the high press re calibra-
tor together with an external press re
so rce.
Do not remove any connected compo-
nents (e.g. test objects) when the high
press re calibrator is nder press re.
Open the screwed sealing pl g before
removing parts.
Do se Teflon tape to seal the
press re connection caref l. Resid es
of Teflon tape co ld penetrate the
high- press re calibrator and damage
it.

The temperature regulator is a high quality control instrument for both simple ON/OFF two-position regulation or, if desired,
PID control systems with autotuning function.
In the ON/OFF mode, the degree of hysteresis is freely programmable. In the ON/OFF mode, the degree of hysteresis is
freely programmable
The temperature regulator has been designed for heating and cooling operations in the range -200°C to +1, 50°C. The measurement
range is only determined by the type of sensor used.
It is easy to operate and configure, and is ideal for industrial use thanks to the many important customisation options it offers. These
include useful additional functions such as sensor break detection with automatic power cutoff, alarm output, maximum or minimum
set value setting and password access etc.
Safety notes:
Do not use the device in explosive atmospheres or in the vicinity of flammable liquids or gases.
Bear in mind that if you are not qualified to work with electricity, this can result in pain, lasting damage to your
health or your death.
This instruction manual assumes that you are qualified to work with electrical equipment. If you are not qualified

The regulator is now back in operating mode, and has saved the changed values ready for use.
Suggestions for selecting the control mo e:
The following information serves to provide an example of temperature regulation for an electric heater, and
is intended to illustrate a possible configuration. Custom applications demand expert knowledge of control
technology, which is beyond the scope of this instruction manual.
The regulator offers you two different options for regulating a set value that you specify either a simple
ON/OFF regulator with hysteresis, or as a PID control system. Before you put the device into operation,
consider which type of regulation would be most appropriate for your particular application.
The ON/OFF regulation with hysteresis is a basic temperature control system in which the regulator allows
the load at the exit (eg heater) to be kept switched on until the preselected set value (menu table A value
SU) is reached. If a hysteresis value (switching delay) is entered in the DFCT menu, this value is added to
the set value. The load is therefore switched off according to the following schema
Set value + Hysteresis value = Load switched off. The load is switched back on again according to the
reverse of that principle Set value - Hysteresis = Load switched back on.
Example
If the set value is 100°C and hysteresis is 0.5°C, the load is switched off at 100.5°C and switched back on at
99.5°C.
This basic regulation is ideal for lots of applications. Its advantage lies in its easy to understand functioning,
plus in its low switching rate and, if mechanical load protectors are used, protection of the load relays that
switch the load.
Switching rates can be minimised by setting as high a rate of hysteresis as possible.
The disadvantage of ON/OFF regulation is that the temperature fluctuates in the range around the set value,
due to the hysteresis that was specified and the sluggishness of individual process components (heater
follow-up time, sensor reaction times, loss of transmission etc).
A PID control system is ideal for many applications, as it can achieve highly consistent temperature values
without fluctuation. In contrast to ON/OFF regulation, this process uses software in the regulator which, when
a load is connected, records the process conditions required for controlling (autotuning function, p5). The
regulator’s software then determines the appropriate PID parameters, which, thanks to special algorithms,
reduce the heat output step by step as the temperature converges with that of the set value.
Reduction occurs by pulsing on the controller output. In an ideal scenario, when the temperature reaches the
set value, the regulator only releases the heat output that is required to maintain the preselected
temperature.
The PID control system is therefore most appropriate when the connected load needs to be triggered at short
intervals using on/off intervals. The advantage of this method lies in the fact that the temperature curve
achieved is very linear, and generally permits only the most minimal fluctuations, with a tolerance of just a
few tenths of a degree.
In many processes, PID regulation requires extremely short switching times, sometimes < 1 sec. Due to
regular pulsing, mechanical relays are subject to a high rate of wear and tear. The temperature regulator has
been designed for triggering an SSR relay (as used in calibrator PPS1210). This enables you to even switch
greater loads with short pulse times, and without wear and tear, thanks to electronic thrysistor switches.
Because certain applications also require the use of regulators with SSR output and semiconductor relays to
trigger mechanical load protectors, the regulator also features a function enabling you to preselect a
minimum pulse time (menu table B – Switching time output (T). Particularly if you are using mechanical load
protectors, this allows you to specify a minimum switching time. The correct setting for your particular
application depends on making a considered compromise between the shortest possible switching time, to
ensure a linear set value progression, and the shortest possible switching frequency, which will prolong the
lifetime of the downstream relay contacts. When using PID controls, a larger safety clearance between the
switching load and the mechanical relay’s specified nominal load is recommended.

Using the menus:
The temperature regulator is operated via two menus (A and B). Menu A contains the settings for the set
value (see also page 19 ‘Changing the set value and alarm temperature’). These settings are easily
accessible to any operator by simply pressing the button to call them up. Repeated pressing of the button
moves to the next menu item.
The parameters in menu B are settings for configuration of the regulator, along with other advanced
parameters. As a rule, these are not operating functions. Access to menu B is therefore password protected,
by calling up ‘Loc’ and entering the password 508 (see next page).
The ‘Loc’ menu also provides you with the option to prevent the set value (menu A) being changed, should
you wish that operators are not permitted to change it. To do so, set a value other than 0 (not 508).

Example of a heating control system on output relay terminal 1, 2
Operating mode ON/OFF (BITR), set value = 200.0°C, DFCT = 0.5°C
The output relay will therefore switch off the heating when 200.5°C is reached;

OFF No alarm active (alarm output on terminals 6, 7, 8 is deactivated)
HJ Absolute alarm value excess temperature (high limit)
Alarm is emitted when the alarm value specified is reached. Alarm stops automatically according to
the preselected switching hysteresis (DFAL menu)
HJB Absolute alarm value excess temperature with hold function
As per HJ above, except that when the regulator is switched on (control voltage on), the alarm does
not emit immediately, even if at the time of switching on the temperature is such that the alarm would
usually be triggered during normal operation (for example, if a refrigerator is still warm).
The alarm will only be emitted if the temperature moves out of the normal range and heads
towards the alarm setting (temperature slope runs up to the alarm setting). Automatic alarm reset in
accordance with DFAL menu. LJ Absolute alarm value insufficient temperature (low limit)
Alarm is emitted when the lower alarm value specified is reached. Alarm stops automatically
according to the preselected switching hysteresis (DFAL menu)

t switching time output
(T) 2-120s
T represents the minimum period of time in seconds in which the output remains switched on. In
principle, when using mechanical relay outputs/switching mechanical load relays, you should select
the longest possible switching time, in order to avoid premature wear due to high switching
frequency.
When using regulators with SSR outputs and so-called SSR relay leads, in many cases selecting a
shorter pulse interval results in better linearity of the temperature curve. Thanks to wear-free
switching provided by electronically switching SSR relays, it is possible to choose your own
switching frequency.

‘Automatic a justment’ (Autotuning) function
The control panel features a programme that automatically finds the optimum PID settings for the connected load.
For this programme to work, it is important that the regulator is ready for operation, the load is connected and that a
non-critical temperature set value has already been set. In the ‘Loc’ menu (page 20), the value 0 must be set.
When in autotuning mode, the regulator moves through one or more control cycles so that it can establish the
parameters. This can result in considerable deviations from the set value. Bear this in mind when specifying
the set value. In consideration of this, it should be as close as possible to the actual control value.
During normal operation when a load is connected, press the button for about 4 seconds.
In the SV display, the set value flashes in alternation with - AT -. The procedure is complete once SV has
automatically returned to normal display.
In order to cancel autotuning, press the button again for about 4 seconds, until SV stops flashing. The
previous settings are not changed.
Alarm output configuration:
As well as an SSR output, the TR-81 also features an alarm output (terminals 8, 7, 6), which can be provided with its
own set value (Menu B, parameter AL1T) as well as its own hysteresis (Menu B, parameter DFAL). When making
any such settings, refer to the information provided in menu table B, under parameter point ALT1.
If, when the regulator is switched on, an undesired alarm is emitted (when the set value at the time of switching on
corresponds to the alarm value), this can be prevented by the HJB setting (if the alarm range is higher than the set
value) or the LJB setting (if the alarm range is below the set value). Both these settings can be found in menu AL1T.
These settings enable the alarm to be temporarily bypassed after the control voltage has been switched on.
Maintenance an customer service:
In normal operation, the TR-81 regulator does not require maintenance. Excessive dust deposits should however be
avoided. Use in wet rooms is only permitted with the approved housing with protective cover (part no Z-45-
KsKap45x45). Electronic components must be protected against condensation moisture.
Dirt on the front and on the housing can be removed with a slightly moistened cloth when the regulator is switched
off.
