ER09 / ER19 Electronic Proportional Regulators FRL-SIF-621
Applications for this innovative product in the Automotive industry can
be seen in major manufacturers’“body-in-white” lines.
The control of clamping and welding forces during panel assembly is
an ideal application, also accurate control in paint dipping and spraying
can be achieved.
The Packaging and Food industry provides another ideal area for
application of the Electronic Proportional Regulator, where fine control
of tension on wrapping foils and paper is required.The degree of control
and the ability to manually change parameters makes this unit ideally
suited to the varying requirements of this industry.

Why Proportional Technology ?
The Difference Between Open or
Closed Circuit Control
Standard pressure regulators go a long way towards
meeting customers needs.In most cases these
regulators work well in general pneumatic and
automation applications.However, sometimes the
application calls for more precise pressure control.
The effects of time, cycling, input, back pressure or
pressure and flow variation can all cause inconsistencies
in pneumatic systems.Proportional Regulators are
designed to eliminate those inconsistencies.
Open Control Circuit
In a normal pressure regulated control system, the inlet
pressure (p1) is converted into the output pressure
(p2) by the regulator.The set pressure (set value) is
usually manually set by adjusting the control knob and
in normal circumstances the regulator maintains the
output pressure (actual value).
No facility for monitoring the output pressure is
provided and there is consequently no way of checking
that the set value and the actual value are the same.
Also, no account is taken of external influences such as
air consumption by the system, which can drastically
alter the actual value.
Typical Application in Automotive Body in
WhiteWelding Pressure Control
Closed Loop Control Circuit
The input signal (Electronic Control Signal) is
converted into the output value (P2 Output Pressure).
This output value is continuously measured and
compared with the input signal. If they are different, the
unit adjusts the output value to correspond to the set
value, to close the loop.
Proportional Pressure Regulators
The Proportional Regulators provide all the advantages
of a closed circuit regulated system.When a set value
is defined via the input signal (e.g.0-10 V), the pressure
regulator sets the corresponding output pressure (e.g.
0-150 PSI/0-10 bar). At the same time the integrated
pressure sensor measures the actual pressure at the
unit’s outlet (actual value).
If the electronic regulation system finds that the actual
value has deviated from the set value, it immediately
corrects the actual value.This is a continuous process
ensuring fast, accurate pressure regulation.

Advanced Functionality
PilotValve Protection
When the required output pressure can not be
achieved due to lack of input pressure, the unit will
open fully and will display “NoP”.Approximately every
10 seconds the unit will retry.The output pressure will
then be approximately equal to the inlet pressure. As
soon as the input pressure is back on the required
level, the normal control function follows.
Safety Exhaust
Should the control signal fall below 0.1 volts, the
valve will automatically dump downstream system
pressure.
Input Protection
The unit has built-in protection against failure and
burnout resulting from incorrect input value, typically:
The 24v DC supply is incorrectly connected to the
setpoint input, the display will show ‘OL’, as an
overload indication. The unit will need to be rewired
and when correctly connected will operate normally.
The overload indicator ‘OL’ will also appear should the
wrong input value be applied or the wrong input value
be programmed: 4 - 20m instead of 0 - 10V. To correct
this a different set point value should be input or the
unit reprogrammed to correct the set point value
acceptance. (via parameter 4).

Behavior Control
The regulation speed of the pressure regulator can be
modified by means of one parameter. (P 20)
The value in this parameter has a range from 0-5. A higher
value indicates slower regulation speed, but will be more
stable.
* When the value 0 is entered, you are able to create your own custom settings true parameters 12, 13 and 21.
Set Pressure Correction
Pressure correction allows the user to set a maximum
pressure as a percentage of secondary pressure F.S.
Example: If F.S.is 10 bar, set parameter 19 to 50 for
maximum preset pressure of 5 bar.
Pressure correction also affects the minimum preset
pressure in parameter 18.
Example: If F.S.is 10 bar and parameter 18 is set to a value
of 100 (1 bar), and parameter 19 is set to 50%, then the
actual minimum preset pressure seen is 0.5 bar.

Problem Possible Reason Solution
Display will not light up No 24 volts power supply Check if the wiring is connected according to
the schematic wiring diagram
Unit will not, or not correctly respond to
given setpoint Wrong current applied ( I.e.Volt instead of mA or mA instead of Volt Change setpoint current or re configure the setpoint current through the software by
changing parameter 4
Check wiring if the setpoint signal lead is
connected to the right pin within the male
M12 connector ( should be pin 2)
Setpoint signal is not stable enough Stabilize setpoint signal input
Display shows NoP. Unit detects that required output pressure is
higher than the supplied pressure Adjust the inlet pressure to a higher value, preferably 0,5 bar higher than requested
output pressure
Give lower setpoint value which corresponds
to a output pressure lower than the inlet
pressure
No inlet pressure at all Connect port 1 to the supply pressure
Unit behavior is not considered normal Faulty settings made in the parameters Reset the unit to factory settings by using the
green key function under parameter 0
Desired pressure can not be reached Setpoint value to low
Pre-set pressure limit has been changed to a
lower max.outlet pressure
Increase setpoint value
Change max. outlet pressure back to re-
quired pressure by changing parameter 19
Supply pressure is to low Increase supply pressure
Secondary side stays pressurized Setpoint value is higher than 0,1Volt
Pre-set pressure has been enabled to a
certain pressure
Lower your setpoint value, preferably to 0
Volts
Reset parameter 18 to 0
Display shows unrealistic value Display maybe configured in the wrong value
( bar instead of psi) Check through parameter 14, if the display value is set on either psi or bar, if necessary
change it to the required setting
Unit response time too slow or too quick Volume behind the unit is either too big or
too small Adjust the regulating speed of the unit through parameter 20
Unit gives too much overshoot Relation between volume and response me
is out of balance Adjust response time to a higher value through parameter 20, to achieve more ac-
curate behavior
Unit is adjusting/regulating constantly Air leakage in the system behind the unit
Constant changing volume behind the unit
“Deadband “area is set too small
Resolve leakage
Unit needs to regulate to keep required pres-
sure at the same level
Try to minimize the volume changes
Enlarge deadband setting through parameter
13 in the software ( parameter 20 has to be
set to 0 before changing parameter 13)
Can not enter software through touchpad Unit is currently working/processing Make sure that the unit is in steady state
while activating the software
Activating time is too short Hold the accept button for at least 3 seconds
Display indicates‘OL’ Wiring not according to diagram (24 volt con-
nected on the setpoint connection pin) Rewire so that on the setpoint connection pin will be either 0-10v or 4-20mA
Wrong setpoint value given in relation to
programmed setpoint value acceptance Change over setpoint value to eitherV or mA or Reprogram the unit to the correct setpoint
value via parameter 4
Any other problem Please consult factory

Glossary
Hysteresis – The mechanical limits of accuracy of
the unit. The regulator cannot be adjusted within the
inherent mechanical limits of the design.
Dead Band – The minimum limit of accuracy at which
the regulator is set for normal operation. This band
must be equal to, or exceed, the inherent design limits
of the regulator or the hysteresis band.
Proportional Band – The band used for setting
reaction sensitivity of the regulator. The regulator
senses the excursion from the set pressure and adjusts
response in relation to the degree of excursion beyond
the dead band. This band must exceed the dead band
of the unit.
Proportional Effect – The speed at which the unit
approaches P2 (secondary pressure).
Sensitivity –
The smallest change in the control signal,
or feedback signal, to cause a change in regulated
output pressure.
Repeatability – a measurement of how consistently
the unit can reproduce an output pressure in relation
to a specific set pressure.
Linearity – A measure of how closely the relationship
of output pressure vs.the control signal deviates from
a straight line function.
PNP Output – Referred to as a “Sourcing” open
collector transistor output where the voltage sources
towards 24VDC when activated.
NPN Output – Referred to as a “Sinking” open
collector transistor output.The output sinks towards
0VDC when activated.
