Proportion-Air ISQB1 Installation and operating instructions

1ISQB1 Installation Guide - 2/13/2015 | SSS
DESCRIPTION / IDENTIFICATION
The ISQB1 series control valve is an electronic
pressure regulator designed to precisely and
proportionally control the pressure of gaseous media
based on an electronic control signal.
The ISQB1 operates using two normally closed
solenoid valves, a pressure sensor, and a control
circuit. One valve is actuated to allow supply media
into the system. The second valve is actuated to allow
working media to vent through a threaded port to
atmosphere. The pressure sensor provides feedback
to the control circuit. The control circuit compares the
pressure sensor feedback to the user supplied
electronic command signal and actuates the
appropriate valve until the two signals match.
The ISQB1 series can be teamed with a variety of air
piloted pressure volume boosters for even greater
flow.
† Pressure ranges are customer specified. Output pressures other
than 100% are available.

pressure.
3. Connect the “OUT” OUTLET PORT (figure 1) to the
device being controlled.
4. Media vents through exhaust port. If the media is
hazardous (classified), the threaded exhaust port
(figure 1) should be vented into a safe area.
5. Proceed with electrical connection.

5. Set the electrical command input to 20mADC. Adjust
the SPAN potentiometer until MAXIMUM desired
pressure is reached (clockwise to increase pressure).
6. Set the electrical command input to 10 percent of full
value (5.6mA).
7. Adjust the ZERO potentiometer until 10 percent of
maximum desired pressure is reached. (clockwise
increases pressure).
8. The ZERO and SPAN potentiometers interact slightly.
Repeat steps 5-10 until no error exists.
9. Verify unit shuts off by going to 4mADC command.
Check linearity by going to at least six pressures
throughout the full range.
NOTE: Only use this step if your device is totally
out of calibration. If it is slightly out of calibration,
omit this step and move on to paragraph 5. Using a
small screwdriver, turn both potentiometers 15 turns
clockwise. Then turn them 7 turns counter clockwise.
This will put the ISQB1 roughly at mid scale.
Re-calibration:
1. Wire the ISQB1 according to the section titled
“Electrical Connections.”
2. Connect a precision pressure gage or pressure
transducer to the OUTLET PORT of the ISQB1.
NOTE: There must be a closed volume of at least
1 in3 between the OUTLET PORT and the measuring
device for the ISQB1 to be stable.
3. Provide supply pressure to the INLET PORT of the
ISQB1. (See figure 1). Make sure supply pressure
does not exceed the rating for the valve. (see table 1)
All ISQB1 valves come calibrated from the factory by
trained personnel using precision calibration equipment.
The ISQB1 is a closed loop control valve using a
precision electronic pressure sensor. Typical drift is less
than 1% over the life of the product. If your ISQB1
appears to be out of calibration by more than 1%, it is not
likely to be ISQB1. Check the system for plumbing
leakage, wiring and electronic signal levels. Verify the
accuracy of your measuring equipment before re-
calibrating. If the ISQB1 valve needs re-calibration, use
the procedure described below:
RE-CALIBRATION PROCEDURE
4. Remove the zero and span plug on top of the ISQB1
to access the ZERO and SPAN adjustment
potentiometers (figure 1).

Improper operaon could result in serious injury to persons or
loss of life!
1. PRODUCT COMPATIBILITY
Proporon-Air, Inc. products and accessories are for use in
industrial pneumac applicaons with compressed air
media. The compability of the equipment is the
responsibility of the end user. Product performance and
safety are the responsibility of the person who determined
the compability of the system. Also, this person is
responsible for connuously reviewing the suitability of the
products specied for the system, referencing the latest
catalog, installaon manual, Safety Precauons and all
materials related to the product.
2. EMERGENCY SHUTOFF
Proporon, Inc. products cannot be used as an emergency
shuto. A redundant safety system should be installed in
the system to prevent serious injury or loss of life.
3. EXPLOSIVE ATMOSPHERES
Products and equipment should not be used where
harmful, corrosive or explosive materials or gases are
present. Unless cered, Proporon-Air, Inc. products
cannot be used with ammable gases or in hazardous
environments.
4. AIR QUALITY
Clean, dry air is not required for Proporon-Air, Inc.
products. However, a 40 micron parculate lter is
recommended to prevent solid contaminaon from
entering the product.
5. TEMPERATURE
Products should be used with a media and ambient
environment inside of the specied temperature range of
32°F to 158°F. Consult factory for expanded temperature
ranges.
6. OPERATION
Only trained and cered personnel should operate
electronic and pneumac machinery and equipment.
Electronics and pneumacs are very dangerous when
handled incorrectly. All industry standard safety guidelines
should be observed.
7. SERVICE AND MAINTENANCE
Service and maintenance of machinery and equipment
should only be handled by trained and experienced
operators. Inspecon should only be performed aer
safety has been conrmed. Ensure all supply pressure has
been exhausted and residual energy (compressed gas,
springs, gravity, etc.) has been released in the enre
system prior to removing equipment for service or
maintenance.
Warning
Improper operaon could result in serious injury to persons or
damages to equipment!
1. PNEUMATIC CONNECTION
All pipes, pneumac hose and tubing should be free of all
contaminaon, debris and chips prior to installaon. Flush
pipes with compressed air to remove any loose parcles.
2. THREAD SEALANT
To prevent product contaminaon, thread tape is not
recommended. Instead, a non-migrang thread sealant is
recommended for installaon. Apply sealant a couple
threads from the end of the pipe thread to prevent
contaminaon.
3. ELECTRICAL CONNECTION
To prevent electronic damage, all electrical specicaons
should be reviewed and all electrical connecons should
be veried prior to operaon.
