5.12.5 Calibrate measurement of mid voltage
Here you calibrate the monitoring unit's measurement instrument for battery
mid voltage to ensure the measurement value matches the actual mid
voltage. This is done on delivery from the factory, but can also be done
during the stipulated routine inspections.
Connect a voltmeter either between the battery's negative terminal and the measurement point of
the mid voltage or to the rectifier's connection block for mid voltage measurement. 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.
To facilitate calibration with a stable level of the 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.
5.12.6 Lamp test
For test of indication lamps on rectifiers and monitoring unit.
Use the buttons ”↓” and ”↑” to select between the alternatives Normal and
On, where On turns all lamps on. After finishing the test by pressing OK, the
lamps will return to normal state.
Note: Only relevant for monitoring unit PCM2 and rectifier module type PCV and PRM3.
5.13 FUNCTIONS
5.13.1 General
Here you can select the conditions that are to apply for
the functions that are available in the monitoring unit.
If PCM2 is used solely as a monitor (number of rectifiers
= 0) the Battery circuit test, Equalizing charging, Uminimum, Umaximum and RI-compensation
options cannot be selected.
5.13.2 Select language
Select the language to be used for the display.
5.13.3 Parameters for mid voltage measurement
Here you enter the conditions that apply for measuring
the battery's mid voltage.
Start by specifying whether the measurement input is to
be connected to the battery or not. If not, the “Symmetry
fault” alarm will lose its function.
As it is not always physically possible to connect to the battery's theoretical
midpoint, you must specify where the measurement connection in practice
occurs. You do this by specifying as a percentage what proportion of the total
battery voltage is expected at the measurement point. First calculate the
percentage using the following formula:
