Installation
Note: When changing the type of sensor (e.g. from a 31xxx EC sensor to a 31xxxS smart EC sensor)
please contact your local Hach Lange representative.

Analog inputs (when ext. press. sensor is
directly connected)
12. EC sensor: Not used
TC sensor: GND
13. Green: Input ext. press. sensor P+
14. White: Input ext. press. sensor P-
15. Red: Output ext. press. sensor +
16. Black: Ground (GND)
Analog inputs (when ext. press. sensor
extension, Part N° 32548.xx, is used)
12. EC sensor: Not used
TC sensor: GND
13. Green: Input ext. press. sensor P+
14. Yellow: Input ext. press. sensor P-
15. White: Output ext. press. sensor +
16. Brown: Ground (GND)
Note: On multi channel systems, the external pressure sensor must be wired to the channel 1
measurement board, but the signal is used to compensate all channels.
Connector J8 (sensor)
Note: Remember, this connector is colored orange for EC sensors and black for TC sensors.

Figure 21 Output relays
The three output relays are located on the measurement
board (see also
Figure 17 and Figure 18 on page 38 ).
They can be individually configured to Normally Open (NO) or
to Normally Closed (NC) by physically moving the jumper on
each relay. The picture example on the left (EC measurement
board):
• Upper relay is set to NC
• Middle relay is set to NO
• Lower relay is shown with no jumper, to show the 3 pins.
Note: For all measurement boards, J4 is relay 1, J5 is relay 2 and J6
is relay 3
