• IMPORTANT: Refers to essential information for the user.

Installation:

CAUTION: Avoid jolts and heavy vibrations during transport to prevent damage to internal parts. Only install and electrically connect the pressure switch as instructed. Follow these steps:

1. The switch may only be installed in systems where the maximum pressure Pmax is not exceeded (refer to type label).
2. Install the switch only when de-energized both electrically and hydraulically/pneumatically.
3. Mount the pressure switch from the bottom to the fitting using a wrench SW 27 and tighten it to a torque of 45 Nm.

FAQ:

• Q: Can the dual pressure switch be used as the only safety device in pressurized systems?
  A: No, the switch is not designed to be used as the only safety device according to Pressure Equipment Directive 97/23/EC (PED).

• Q: What should I do if I exceed the rated pressure values?
  A: Do not exceed rated pressure values as it may result in damage to the switch. Ensure that pressures are within permissible limits.

• Q: How should I dispose of the pressure switch?
  A: The switch must be disposed of correctly according to national or local regulations for electric/electronic equipment. Do not dispose of it with household trash.

Intended Applications

The dual pressure switch monitors system pressures 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)”.

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 by the national or local regulations for electric/electronic equipment.
• The switch must not be disposed of with household trash!

Standards

The standards applied during development, manufacture, and configuration are listed in the CE conformity and manufacturer’s declaration.

Warranty/Guarantee

Our scope of delivery and services is governed by legal warranties and warranty periods.

Terms of guarantee
We guarantee for function and material of the dual pressure switch under normal operating and maintenance conditions by the statutory provisions.

Loss of guarantee
The agreed guarantee period will expire in the 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”

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).
• Mount the pressure switch from the bottom to the fitting using a wrench SW 27 and tighten it to a torque of 45 Nm.

IMPORTANT

• In the pressure inlet a damping screw made of brass is mounted. This screw can be removed if required, e.g. in case of soiled medium or material incompatibility, using a slotted screw driver (max. width 3 mm).
• The pressure switch is less resistant to pressure peaks when the damping screw has been removed.

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.

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!

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 signalled in the display by “Err” and the corresponding message, refer to Error list on page The red LEDs S1 and S2 signal the activity of the two switching points.
Operation is menu-driven via three keys:

CAUTION
Do not use any pointed, hard objects for making entries. The keys may be damaged by pointed, hard objects.

For information about the factory settings for the parameters and how to change them please refer to the next chapter 7 “Programming”.

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
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 the 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

Decommissioning

DANGER
Only remove the switch when de-energized (electrically and hydraulically/pneumatically).
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!
