Intended Applications
The dual pressure switch monitors system pressures and has up to two switching outputs and one analog output.
Operate the switch exclusively in the specified fields of application (see chapter “Technical Data“ on page 12).
Observe the applicable national safety regulations for assembly, commissioning and operation of the switch.
Do not use the switch as the only safety relevant element according to DGR 2014/68/EU (PED).
Safety Instructions
The safety instructions are intended to protect the user from dangerous situations and/or prevent material damage.
In the operating instructions the seriousness of the potential risk is designated by the following signal words:
Refers to imminent danger to life and health of men.
Nonobservance will result in serious injuries, or even life-threatening injuries and death
Refers to a potential hazard.
Nonobservance may result in serious injuries, or even fatal injuries and death
Refers to a potential hazard.
Nonobservance may result in light injuries.
Refers to a potential hazard.
Nonobservance may result in damage to the switch and/or to the plant.
Refers to important information essential to the user
![]() | Disposal The switch must be disposed of correctly in accordance with the local regulations for electric/electronic equipment. The switch must not be disposed of with the household garbage! |
Standards
The standards applied during development, manufacture and configuration are listed in the CE conformity and manufacturer’s declaration.
Warranty/Guaranty
Our scope of delivery and services is governed by the legal warranties and warranty periods.
Terms of guaranty
We guaranty for function and material of the dual pressure switch under normal operating and maintenance conditions in accordance with the statutory provisions.
Loss of guaranty
The agreed guaranty period will expire in case of:
- incorrect use,
- incorrect installation or
- incorrect handling or operation contrary to the provisions of these operating instructions.
No liability is assumed for any damage resulting therefrom, or any consequential damage.
Refer to Barksdale “Standard Terms and Conditions“.
Installation
Jolts and heavy vibrations must be avoided during transport. Even if the switch casing remains undamaged, inside parts may be damaged and cause malfunctions.
The pressure switch may only be installed and electrically connected by trained and instructed staff according state-of-the-art standards.
Electric shock and/or explosion!
Install the switch only in systems where the maximum pressure Pmax is not exceeded (see type label). Only install the switch when deenergized (electrically and hydraulically/pneumatically). Mount the pressure switch from the bottom to the fitting using a wrench SW 27 and tighten it to a torque of 20 Nm. The damping screw from brass installed in the pressure inlet can be removed if required, e. g. soiled medium or material incompatibility, using a slotted screwdriver (max. width 3 mm). Attention: Removing the damping screw will reduce the resistance of the device against pressure peaks.
Electrical connection is to be carried out dependent on the type of switch (see type label) according to the chart below. Wrong assignment of the connections may cause malfunctions or incorrect switch outputs.

Commissioning / Operation
The pressure switch may only be commissioned and operated by authorized staff.
Hot surfaces!
During operation with higher temperatures the casing surface may become very hot! Wear protective gloves!
Electric shock!
Do not put the switch into operation when the switch itself or the connection cable is damaged.
After having been switched on the switch runs through a self-test. If thesoftware recognizes an error during the self-test or during operation, this is signaled in the display by “Err“ and the corresponding message, refer to Error list on page 7. The red LEDs S1 and S2 signal the activity of the two switching points.
Operation via three plastic film keys is menu-driven. ▲ , ▼and
The keys may be damaged by pointed, hard objects. Do not use any pointed, hard objects for making entries.
For information about the factory settings for the parameters and how to change them please refer to the next chapter 8 “Programming“.
IO-link version
General information
This device features an IO-link communication interface which requires an IO-link capable module (IO-link master) for operation. The IO-link interface permits direct access to process and diagnostic data and offers the possibility of parametrising the device during operation. Moreover communication via a point-to-point connection using a USB adapter cable is possible.
Device-specific information
The IODDs required for the configuration of the IO-link device and detailed information about process structure, diagnostic information and parameter addresses are available at ->IODD finder and on https://www.barksdale.de/de/download/iolink/. To find the required information please enter the order code in the search mask. IO-link devices manufactured before 04-01 2019 do not support different polarities of the switching outputs.
:Since process connection, seal and measuring cell have no influence on the IO-link communication you must replace them by “xx”. E.g. BPS38GVM0400BP = BPS38xxM0400Bx
TIP: Use the autocomplete function of the IODD finder by entering the article no. character by character. If your device has been manufactured before 04-01-2019 please take into account that the proposed device ID begins with 0x010.

Clean the devices only at room temperature, never in direct sun light.
The following cleaning agents may impair the condition of components from polycarbonate and shall not be used.
– ZEP Fast 505, Pinesol, Formula 409
– brake cleaner
– halogenated solvents
– strong alkaline solutions
– MEK (methyl ethyl ketone)
– abrasives (abrasive additives)
Decommissioning
Electric shock and/or explosion!
Only remove the switch when deenergized (electrically and hydraulically/pneumatically).
