Notes:
-
Replace the dry, shipping cap membrane with a 2 mil PE (blue) membrane
or 2.0 mil Teflon (gray) membrane following the instructions provided with
the membrane kit.
-
Do not discard the calibration/storage cup. It is used for calibrating and stor-
ing the sensor when not in use.
-
Allow approximately 10 to 15 minutes after the 5200A is powered on, or after
servicing the DO sensor, for the polarographic sensor to stabilize.

YSI 5562 Probe Assembly
The YSI 5562 probe assembly includes DO, temperature, conductivity, pH, and ORP
sensors. 5200A sensor systems are user selectable. The DO sensor is shipped unin-
stalled and with a dry membrane. Install the DO sensor onto the probe assembly.
Instructions are provided with the probe assembly. A new membrane with fresh
electrolyte must be installed on the DO sensor prior to use.

Wiring Information
System components must be wired correctly to ensure reliable performance and
accurate data collection. Directions are provided in this section for wiring all com-
ponents and peripheral devices.
PCBs
There are three printed circuit boards (PCBs) inside the 5200A enclosure. They are:
-Display board (mounted in the front panel)
-I/O board is attached to a metal plate inside the enclosure and is visible when front
panel is removed
-Control board (connected to the under side of the I/O board)
Notes:
-
I/O and Control boards are attached to a metal plate and are referred to as the
“lower board assembly”. See
Control Board
- page 41.
-
No 5200A components or peripheral devices are wired to the display board.
Most components including: power, Aux input, network, relay output, and RS232
communication components are terminated on the I/O board. 5X00 ground wire
and sensor ground wires (also called drain wires) are terminated to the metal plate
that is attached to the lower board assembly. The optional serial to ethernet device is
installed on the control board. The front panel must be removed when wiring 5200A
components and peripheral devices (except for the probe assembly). See Accessing
the I/O Board - page 39. It is recommended that some system configuration and
