Installation

3.1.

Installation Checklist Monitors

Check

Instrument’s specification must conform to your power ratings.
Do not switch on power until all external devices are connected.

Installation

The transmitter is intended for panel mounting. The dimensions
are shown in

Dimensions of the AMU Transmitter, p. 23

Electrical Con-
nections

Connect all external devices, see

Electrical Connections, p. 32

.

Connect the power cord, but do not switch on power until all
external devices are connected.

pH/ORP
sensor

Install the sensors, see

Flow Cell QV-Flow, p. 25

or

.

Connect the sensor cables.
Store the protective caps for later use.

Power-up

Turn on the sample flow and wait until the flow cell is completely
filled.
Switch on power.
First, the transmitter performs a self test, displays the firmware
version and then starts normal operation.

Instrument
set-up

Adjust sample flow. Program all parameters for sensor and
external devices (interface, recorders, etc.). Program all param-
eters for instrument operation (limits, alarms).

Run-in period

Let the instrument run continuously for 1 h.

pH sensor
calibration

Perform standard calibration or process calibration according to

Calibration, p. 48

ORP sensor
calibration

Perform standard calibration or process calibration according to

Calibration, p. 48
