Wiring Instructions
Sensor to Converter Connection
There are several options for the Sensor to Converter
interface.
•
HML210 Converter mounted integrally on the sensor
(compact).
• HML210 Converter mounted remotely from the
sensor (remote). This requires cable assemblies
C015 and C016.
• HML210 Converter mounted remotely from the
sensor in a panel (remote).
If the HML210 is mounted remotely from the sensor, the
following guidelines must be adhered to:
•
Maximum distance from the HML210 to the sensor
is 30 ft for fluids with a conductivity less than 200µS
(micro siemens).
• Maximum distance from the HML210 to the sensor
is 65 ft for fluids with a conductivity greater than
200µS.
For applications where these conditions are not met, a
preamplifier is required. This mounts directly on top of
the sensor. With a preamplifier installed, the maximum
distance from the sensor to the HML210 is 1,640 ft
(500m).
NOTE : For proper installation, the cables must be ordered
with the unit. User supplied cables may void warranty
coverage and could affect the functioning of the meter.
Preamplifier Version
NOTE: Maximum length of cable C014 is 1,640 ft (500m).
