EL 9000 B HP Series
Setting P. Description
PSI / ELR system 9 This item will only be displayed if the device is set as MASTER
Whenactivatedbyngertouch(checkmark),itdeterminesthattheelectronic
load is part of a two-quadrant operation (2QO, see „3.11.3. Two quadrants
operation (2QO)“) system and thus it will be slave on the Share bus, which is
required for a 2QO, because in 2QO all load units have to be slaves.
Repeat master init. 10 Touch area “Initialize” will repeat the initialisation of the master-slave system
in case the automatic enumeration of the slave units by the master is once
unsuccessful so the system would have less total power than expected or has
to be repeated manually in case the master unit couldn’t detect a missing slave
3.4.3.2 Menu “User Events”
See „3.6.2.1 User dened events“ on page 56.
3.4.3.3 Menu “Proles”
See „3.9 Loading and saving a user prole“ on page 58.
3.4.3.4 Menu “Overview”
This menu page displays an overview of the set values (U, I, P or U, I, P, R) and alarm settings as well as adjust-
ment limits. These can only be displayed, not changed.
3.4.3.5 Menu “About HW, SW...”
This menu page displays an overview of device relevant data such as serial number, article number etc., as well as
an alarm history which lists the number of device alarms that probably occurred since the device has been powered.
3.4.3.6 Menu “Function Generator”
See „3.10 The function generator“ on page 59.
3.4.3.7 Menu “Communication”
Thissubmenuoffersglobalandspecicsettingsfordigitalcommunicationviathebuilt-inUSBinterfaceandthe
optional modular interfaces of the IF-AB series. For IF-AB interfaces there will be a dedicated button which opens
one or more settings pages, depending on the interface in use. There is furthermore an adjustable communication
timeout, to make it possible to successfully transfer fragmented messages (data packets) using higher values. In
the screen for “Com Protocols” you can enable both or disable one of the two supported communication proto-
cols, ModBus and SCPI. This can help to avoid mixing both protocols and to receive unreadable messages, for
example when expecting a SCPI response and getting a ModBus response instead.
For all Ethernet interfaces with two ports: „P1“ is related to port 1 and „P2“ to port 2, like printed
on the module face. Two-port interfaces will use one IP only.
