Rectifier module type PCV and older models of PRM3
The available data from the rectifier unit is stored in what is called a RAM
variable. The variables are 8 bits long and have an address range from 0 to
255. A table describing the variables can be found in Appendix_D.
Select variable address using the “↓” and “↑” buttons. Two variable
addresses, i.e. a total of 16 bits are displayed at a time. The lower of these
two addresses (even numbers) are displayed as bit no. 0-7 while the higher (odd numbers) are
displayed as bit no. 8-15.
The row with individual bits starts with bit 15 to the left and ends with bit 0 to the right.
The row below shows the variable in decimal format in three ways. In the middle the whole 16
bits value of the two addresses is shown, to the right the 8 bits value of the lower address and to
the left the 8 bits value of the higher address.
5.7.4 Show insulation
Shows the system's earth fault resistance as positive and negative directly in
kΩ and MΩ. If the resistance exceeds 5 MΩ, >5 MΩ is shown instead.
At closed down earth fault measuring (see section 4.4.4.2), “__” is shown instead of the value.
5.7.5 Show statistics
5.7.5.1 Menu option
Select from the menu options Mains fault, External faults and Operating time.
If PCM2 is used solely as a monitor (number of rectifiers = 0) the Mains fault
option cannot be selected.
5.7.5.2 Mains fault
For mains power failure, the total number, when the last fault occurred and
how long it lasted are shown.
5.7.5.3 External fault
Shows the number of events that have occurred for the digital input for
external faults (see section 6.4.4.5).
5.7.5.4 Operating time
Shows the following operating times:
1. Total operating time.
2. Total operating time for a battery temperature exceeding +25°C.
3. Total operating time for a battery temperature exceeding +30°C.
5.7.5.5 Program version
Shows the current program version in the operator panel and I/O unit.
