5.12.3 Test digital outputs
This menu is primarily intended for testing the external alarm circuits without
the need of invoking actual alarms, and is designed for use chiefly in
connection with installation and commissioning.
In addition to alarm circuits, other digital outputs can be tested in the same
way.
5.12.3.1 Test alarm outputs A-D
By manually forcing the alarm relays you can easily test the external alarm
circuits.
Use the “←” and “→” buttons to move the cursor to the required relay. Now
use the “↓” and “↑” buttons to switch between the options On and Off where
Off is the condition for an active alarm. Complete the process by pressing OK.
The alarm relays are reset automatically to their ordinary position when you leave this menu.
5.12.3.2 Test alarm outputs E-H
It is possible to connect a second I/O unit in order to get four additional
alarm relays, E to H (see also section 5.13.12). They are tested similar to
alarm relays A-D.
This screen is available only if the option second I/O unit is installed.
5.12.3.3 Test other outputs
In the same way as the alarm outputs, you can test the external circuits for the
digital outputs for the battery compartment fan and test mode request. See
also the section 6.4.5 for a more detailed description of the outputs.
5.12.4 Calibrate measuring of battery voltage.
Here you calibrate the monitoring unit's measurement instrument for battery
voltage to ensure the measurement value matches the actual battery voltage.
This is done on delivery from the factory, but can also be done during the
stipulated routine inspections.
Measure the actual battery voltage using an external voltmeter. The voltmeter must have high
ohms, 10MΩ or higher, and have an accuracy of 0.1 % or better. Now slowly adjust the
measurement value on the display using the “↓” and “↑” buttons until it matches the voltmeter as
closely as possible.
Automatic calibration of the internal voltage reference also takes place in the background at the
same time which monitors the functionality of the measurement circuits (see Internal fault, fault
code 2).
To facilitate calibration with a stable level of voltage, all voltage regulation (such as temperature
control) is temporarily shut down as long as you are in this menu screen. You may therefore
experience a voltage level that deviates from the level you had immediately before.
