Inputs and outputs
● One to three measurement channels with hybrid connections for the sensors at the
measuring points
● Two analog inputs per channel for process gas temperature and pressure
● Two analog outputs per channel for gas concentration(s) or for gas temperature and
concentration For selected versions, the transmission can be read out as an alternative.
● Six freely configurable binary inputs per channel for signalling faults or maintenance
requests from external temperature or pressure transducers or sensor purging failure.
● Six freely configurable binary outputs per channel (signalling of faults, maintenance
requirements, function control, transmission limit alarms, concentration limit alarms, store
analog output)
Communication
Network connection: Ethernet (10Base-T) for remote diagnostics and maintenance.
The LDS 6 can be operated remotely via the Ethernet port with a PC running
Windows 95/98/ME or Windows NT/2000/XP. It is also possible to connect the LDS 6 via
modem to the public telephone net. In that case an LDS 6 LAN modem kit is required. Any
external connection requires the optional software LDSComm (LDS Communication Client)
to be installed on the remote computer. All aspects of LDS 6 can be controlled in this way.
For the operation of the LDS 6 using LDSComm software refer to the LDSComm Manual
(A5E02183317).
Maintenance and fault messages
LDS 6 outputs different warnings via relays:
● Need for maintenance (measured value is not influenced)
● Operating error (measured value might be influenced)
