1 Intended Applications
The dual pressure switch monitors system differential pressure and has up to two switching outputs
and one analog output.
DANGER
The switch may only be used in the specified fields of application.
The temperature ranges must be within the permissible limits. Do not exceed rated pressure and
electrical load values.
Observe also the applicable national and local safety instructions for assembly, commissioning
and operation of the switch.
The switch is not designed to be used as the only safety device in pressurized systems according
to “Pressure Equipment Directive 97/23/EC (PED)”.
2 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:
DANGER
Refers to imminent danger to users.
Nonobservance may result in fatal injuries.
WARNING
Refers to a recognizable danger.
Nonobservance may result in fatal injuries, and destroy the equipment or plant parts.
CAUTION
Refers to a danger.
Nonobservance may result in light injuries and material damage to the switch and/or to the plant.
IMPORTANT
Refers to important information essential to the user.
Disposal
The switch must be disposed of correctly in accordance with the national or local
regulations for electric/electronic equipment.
The switch must not be disposed of with the household trash!
3 Standards
The standards applied during development, manufacture and configuration are listed in the
CE conformity and manufacturer's declaration.
4 Warranty/Guarantee
Our scope of delivery and services is governed by the legal warranties and warranty periods.
Terms of guarantee
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 guarantee
The agreed guarantee 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.
See also Barksdale “Standard Terms and Conditions”
5 Installation
CAUTION
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 instructed staff.
DANGER
The switch may only be installed in systems where the maximum pressure Pmax is not exceeded
(see type label).
Only install the switch when deenergized (electrically and hydraulically/pneumatically).
Ensure that the high side of the pressure is installed with respect to the high pressure port.
Incorrect installation could result in damage to the sensor, equipment, and potential injury. High
pressure on low pressure port will result in damage to the sensor.
Install the pressure switch to each fitting using a wrench 22mm or 7/8.

Electrical connection is to be carried out dependent on the type of switch (see name label) according
to the chart below. Improper connections may cause malfunctions or incorrect switch outputs and
damage to the unit.

6 Commissioning/Operation
The pressure switch may only be commissioned and operated by authorized staff.
CAUTION
Do not put the switch into operation when the switch itself or the connection cable is damaged.
WARNING
Be aware of the fact that in case of operation with higher temperatures the casing surface may
become very hot!
Apply high pressure first, followed by the low reference pressure.
After having been switched on the switch runs through a self-test. If the software 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 is menu-driven via three keys: , and
CAUTION
Do not use any pointed, hard objects for making entries. The keys may be damaged by pointed,
hard objects.
7 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.
NOTE: Since process connection, seal and measuring cell have no influence on the IO-link
communication you must replace them by "xx". E.g. BDS375VM0010BP = BDS37xxM0010Bx
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 0x070.

9 Maintenance/Cleaning
Maintenance
The pressure switch requires no maintenance.
WARNING
Check the switch for functioning at regular intervals.
If the switch does not work properly, stop operation immediately.
Cleaning
CAUTION
The switch may be damaged by the use of unsuitable cleaning agents.
The following cleaning agents may be used to clean polycarbonates:
- Mild soap or detergents
- Isopropyl alcohol
After cleaning, immediately rinse with water. Do not leave cleaners on surfaces of products.
Do not clean products at elevated temperatures or under direct sunlight.
The following cleaning agents are known to affect the integrity of polycarbonate components and
should not be used:
- ZEP Fast 505, Pinesol, Formula 409
- Brake Cleaner
- Halogenated solvents (benzene, gasoline, acetone or carbon tetrachloride)
- Strong alkaline
- MEK (methyl ethyl ketone)
- Abrasive substances
10 Decommissioning
DANGER
Only remove the switch when deenergized (electrically and hydraulically/pneumatically).
Reduce the low pressure first, followed by the high pressure.
Disconnection of the switch from pressure and power supply must be carried out by trained or
instructed personnel according to state-of-the-art standards.
WARNING
Be aware of the fact that in case of operation with higher temperatures the casing surface may
become very hot!
