Hach-Lange SC 200 pH_ORP_DO Module User Manual - Manual (Page 4)

Precautionary labels
Read all labels and tags attached to the instrument. Personal injury or
damage to the instrument could occur if not observed. A symbol on the
instrument is referenced in the manual with a precautionary statement.
This symbol, if noted on the instrument, references the instruction
manual for operation and/or safety information.
This symbol indicates that a risk of electrical shock and/or
electrocution exists.
This symbol indicates the presence of devices sensitive to Electro-
static Discharge (ESD) and indicates that care must be taken to
prevent damage with the equipment.
Electrical equipment marked with this symbol may not be disposed of
in European public disposal systems after 12 August of 2005. In
conformity with European local and national regulations (EU Directive
2002/96/EC), European electrical equipment users must now return
old or end-of-life equipment to the Producer for disposal at no charge
to the user.
Product overview
The module, when installed in an sc200 controller, allows an analog
sensor to connect to the controller. For calibration and operation of the
sensor, refer to the sensor user manual for use with the sc200 controller.
Modbus registers
A list of Modbus registers is available for network communication. Refer
to www.hach.com or www.hach-lange.com for more information.
Installation
W A R N I N G
Multiple hazards. Only qualified personnel must conduct the tasks
described in this section of the document.
Connect the sensor to the module
W A R N I N G
Potential Electrocution Hazard. Always disconnect power to the
instrument when making electrical connections.
W A R N I N G
Electrocution Hazard. High voltage wiring for the controller is conducted behind
the high voltage barrier in the controller enclosure. The barrier must remain in
place except when installing modules, or when a qualified installation technician
is wiring for power, relays or analog and network cards.
N O T I C E
Potential Instrument Damage. Delicate internal electronic components
can be damaged by static electricity, resulting in degraded
performance or eventual failure.
To install the module and connect the sensor, refer to the illustrated
steps that follow and the applicable wiring table:
• pH and ORP sensors with attached cables: Table 3
• pH and ORP sensors with removable cables: Table 4
• D5500 series dissolved oxygen sensor: Table 5
Note: Some combination sensors do not have wires for temperature measurement.
If the metal braid of a combination sensor is tinned, cut off the tinned area.
Note: When additional immunity is needed, connect the clear wire with the black
band (pHD sensors only) to the controller chassis.
Note: If the sensor cable is not long enough to reach the controller, an interconnect
cable and junction box are required to extend the distance.
