ER09 / ER19 Electronic Proportional Regulators
FRL-SIF-621
Technical Information
Dead Band
The dead band is preset at 1.3% of Full Scale*,
adjustable via parameter 13.
Accuracy
Linearity: = < 0.3% of Full Scale.*
Proportional Band
The proportional band is preset at 10% of Full Scale.*
Fail Safe Operation
• If the ER09 / ER19 unit has an “0” or “A” in the 12th
digit of the model number
o When the supply voltage drops, the electronic
control reverts to the fail safe mode. The last
known output pressure is maintained at
approximately the same level depending upon
air consumption. The digital display indicates
the last known pressure setting.
o When the supply voltage is reinstated to the
correct level, the valve moves from the fail safe
mode and the output pressure immediately
follows the control signal requirement. The
display indicates the actual output pressure.
o Note: In the event of loss of both power and
inlet pressure the unit will exhaust downstream
pressure.
• If the ER09 / ER19 unit has an “E” in the 12th digit
of the model number
o When the supply voltage drops, the electronic
control reverts to “Forced Exhaust Mode” and will
automatically exhaust the downstream (regulated)
pressure.
o When the supply voltage is reinstated to the
correct level the unit will return to normal
operation and follows the control signal
requirement. The display indicates the actual
pressure.
• If the unit has been programmed in manual mode
(not with a control signal) the unit will EXHAUST
and the regulator will need to be reset when power
is applied.
Full Exhaust
Complete exhaust of the regulator is defined as
P2
≤
1% Full Scale
* Full Scale (F.S.)
For 2 bar versions this will be 2 bar, for the 10 bar
version full scale will be 10 bar.
