2-8 Installation
!
DO NOT twist the cable so that it turns inside the IPS housing.
This may cause permanant damage to the device.
CAUTION
!
Failure to follow these procedures may adversely affect the product’s perfor-
mance and could void the product warranty. Inspect but DO NOT unwrap any
parts until installation. Contact your Brooks representative with any problems.
In most cases, physical mounting, wiring to the power supply and control
circuit, and setting setpoint is all that is required to complete installation of the
IPS pressure switch as received from the factory. Refer to the tag on the back
of the IPS pressure switch for factory configuration of close on ascending or
close on descending pressure.
For some applications it may be necessary to invert operation of the LED
indicator and/or logic signal configuration to ascending or descending
operation, disassembly is required to change internal jumper switches.
2-9 Mounting
Mount the IPS pressure switch to the proper fitting in the piping arrangement
following standard piping procedures.
2-10 Electrical Configuration
The IPS pressure switch contains two internal “jumper switches” to invert
operating functions. Use needle nose pliers to change the switch jumpers.
(Refer to Figure 2-1)
• LED Indicator
A red LED (light emitting diode) indicates when the pressure setpoint is
reached. Its operation is controlled by jumper switch J1. Changing the
position of the internal jumper switch inverts the operation of the LED. For
example, the LED may be set to turn ON when pressure either rises
above or drops below the setpoint.
• Output Switch - Ascending/Descending Operation
The IPS electronic switch may be configured to Close (turn ON) when
pressure either rises above the setpoint (ascending), or drops below the
set-point. (descending). This operation is controlled by jumper switch J2.

NOTICE
Note: Moving the red-pointer does not change the setpoint.
It is merely a visual reminder of where setpoint was previously set.
Before operating the device, ensure all fluid connections have been
properly tightened and where applicable, all electrical connections
have been properly terminated.
WARNING
!
(Typical factory setting is at mid-scale.)
1. Connect the IPS pressure switch to a variable pressure source.
2. Apply pressure equal to the desired setpoint.
3. Slowly turn the setpoint adjustment screw (with a 1/8” or smaller
flathead screwdriver only) until the LED indicator on top of the IPS
pressure switch is activated. DO NOT OVERTIGHTEN.
(Refer to Figure 2-1 for adjustment screw location)
• CLOCKWISE to activate the electronic switch to increase pressure
setpoint.
• COUNTERCLOCKWISE to activate the electronic switch to decrease
pressure setpoint.
4.Change the applied pressure until the gauge is within the normal zone of
operating pressure.
5.Slowly continue to change the pressure and verify that the LED indicator
is activated at the desired setpoint.
6.Repeat pressure cycle to verify setting and readjust if necessary.
7.Adjust the red pointer mounted on the lens cover with a small
screwdriver to indicate the setpoint setting.
DO NOT attempt to adjust the red pointer by rotating the cover.
CAUTION
!
8.On a compound gauge, the zero is indicated by a range on the dial
rather than a setpoint.
9.Clean the non-metallic parts with a damp cloth to avoid electric discharge.
When adjusting the setpoint, DO NOT overtighten the setpoint
adjustment screw in either direction. This may cause permanant
damage to the device.
