General These instructions will enable you to safely install, set 1.1 Information about up and operate the Model 140 electro-pneumatic these instructions converter. These instructions are an integral part of the product and must be accessible to personnel. Personnel must carefully read through and understand these instructions before starting work of any kind on the valves. -
Page 4: Liability And Warranty
1.3 Liability and Modification to the Model 140 converter may only be carried out by the manufacturer’s personnel. If the warranty converter requires repairs or servicing beyond the scope of the activities described in these instructions, this work may only be carried out by the manufacturer of the converter or by persons who have been expressly authorised and trained by the Manufacturer. -
Page 5: Safety
2.1 Intended use The Model 140 converter is a precision electronic pressure regulator which provides an output pressure that is proportional to a given control signal. It is intended for pneumatic applications where fine control of air pressure or regular automated pressure changes are required. -
Page 6: Personnel Requirements
2.3 Personnel WARNING requirements Danger of injury caused by lack of training! People who lack proper training cannot assess the risks when handling the proportional pressure control valves and they place others at risk of serious injury or death. • Have all work on the pneumatic system carried out by pneumatics specialists. -

Page 11: Transport And Storage
Transport and storage Individual packed items are packed according to the Transport expected transportation conditions. Packaging is intended to protect the individual components against transportation damage, corrosion and other damage until they are installed. Only remove the packaging just before installation. Check package on delivery to make sure it is complete and has not been damaged in transit. -
Page 12: Brief User Guide
Brief user guide Please read these instructions carefully BEFORE this instrument is installed or maintained. The Model 140 I/P converters are not intended to be used as a Safety accessory or as a means to isolate equipment from over-pressurisation or under pressurisation. - Page 13 This is a quick guide to connecting the instrument for the convenience of personnel who are familiar with this type of product. More comprehensive instructions are contained later in this manual: 1. Connect a clean air supply of about 2,0 bar (30 psig) to the IN port (1/4”).

Page 15: General Description
General description These converters are precision electronic pressure controllers designed for continuous process control applications. The units operate a closed loop system incorporating a feedback sensor ensuring long term stability and high accuracy performance, with ‘fail-safe’ operation, i.e. the output falls to a low pressure upon failure of the loop current. -
Page 16: Installation
Installation Before installation, For new systems, ensure all connections and lines are please note clean, free from burrs, fluid and debris. Do not remove blanking covers from the proportional valves until just before installation. Mounting The converter must be securely mounted to prevent accidental damage from occuring during operation. -
Page 17: Pneumatic Connection
8.1 Pneumatic connection Improper DANGER! pneumatic connection Danger of injury caused by improper connection! Faulty pneumatic connections can impair the safe operation of the converter and may cause injuries during operation. • Do not install any additional components between the load and the converter. - Page 18 Pneumatic installation These instruments are recommended for use with clean, dry, oil free instrument grade air to BS 6739 or ISA-7.0.01-1996 Dew Point: At least 10°C (18°F) below anticipated ambient temperature. Dust: Filtered to below 50 microns Oil Content: Not to exceed 1ppm mass. The instrument is factory calibrated with a supply pressure of 30 psig (2 bar) ±10%.
- Page 19 Compressed Air WARNING! Danger of injury caused by compressed air! Compressed air can cause injuries if not handled correctly. • Make sure the machine is depressurised before work begins. Personnel: • Pneumatics specialist Protective equipment: • Safety goggles • Protective gloves Connections CAUTION: Avoid damaging the thread when removing the...

-100mA, no operation is possible in this condition. The Model 140 approximates a constant load of 6,5 volts across the loop terminals therefore it is essential that the loop controller be capable of providing a constant current in the range 4 ... - Page 21 WARNING: These instruments must be installed in accordance with local and national codes of practice, especially for hazardous area installations. The electronic circuits are isolated from the chassis and grounding is unnecessary for functional purposes. However, grounding may be necessary to conform to installation codes.

Page 22: Calibration
Calibration Personnel: • Pneumatics specialist Protective equipment: • Safety goggles • Protective gloves • Ear protection The instruments are designed for continuous operation without the necessity for routine overhaul, with continuous monitoring, adequate precautions and replacement of the filter no longer than every 5 years. The most common source of failure for pneumatic instrumentation has been found to be inadequate air quality, allowing contaminants to block internal orifices. - Page 23 If either Span or Zero controls are adjusted it may be necessary to repeat the above steps until both ends are within the calibration limits. Alternatively the jack plug can be connected to calibrate and test the unit. The Jack plug can be be either setup for Monitoring or Calibration/Operation set-up.
- Page 24 Tight shut-off The Tight Shut-Off potentiometer can be adjusted to set the zero point at which the instrument ’shuts off‘. adjustment instructions For Example: Tight shut-off is deactivated in the factory. Setting of shut-off point: 1. With the instrument under test connected to the required supply pressure and load ports, apply a demand current signal of that value at which shut-off is required.

Simple functional checks Apply a 4-20mA signal and an air supply of 30 psig and observe the output on a pressure gauge. It should control smoothly. The Test Jack can also be connected as a monitor measure. 10. Maintenance WARNING: Servicing requirement Risk of injury from using incorrect replacement replacement valves... -
