Position indicator indicates more


Seeing at a glance whether an important valve is open or closed can be crucial. Schubert & Salzer Control Systems has developed the 2040 digital position indicator to provide a totally unique on-site signalling unit. It uses a coloured light signal, visible from a distance, to show the open or closed position of a valve.
 
The digital position indicator has 4 coloured signals. The open and closed positions are indicated by the yellow and green colours. By a simple press of a button, these coloured signals can now represent the end stops. In addition, when the end stops are reached, the digital position indicator outputs this as a switching signal (NPN) to the contacts on the connector plug (M12x1-5pin).
 
Besides open and closed positions, the position indicator also signals maintenance information and issues error messages. Errors are indicated by default by a red lamp and a constant signal at the error message output (NPN).
 
The valve position indicator has an integral maintenance monitor. This enables all activities of the position indicator and, therefore, of the valve, to be recorded permanently. With regards to the digital position indicator, that can be fitted quite as easily as Schubert & Salzer Control Systems GmbH’s digital positioners to linear and part-turn actuators for pneumatic valves.
 
The setting of all parameters from the colour selection (RGB colour scale) to the maintenance values is done by means of a USB adapter with the DeviceConfig adjustment software (from version 7.02.00). The current software version can be downloaded free of charge. Optionally, the digital position indicator is delivered with a Bluetooth communications module so that the parameterising can be done wirelessly in places where access is difficult.
