Wiring
Devices with DC 24V auxiliary supply have to be operated on a galvanic
separated power supply.
Configuration Cycle
1.)
Wire the system
2.)
Adjust module address on extension modules with switch “ADR”
(different addresses for all modules)
2.1) When display units are integrated into the annunciator system the
address setting of each display unit has to be done as follows
- if the display unit should display the state of the base module
(RP 5994) set “MODE” switch on back of the unit to position
“Basismodul” and adjust an address that is not used by any
other display unit.
- if the display unit should display the state of an extension module
(RP 5995) set “MODE” switch on back of the unit to position
“Erw.modul” and adjust the same address as on the extension
module (RP 5995) of which the status should be displayed.
3.)
Set “MODE” switch on base module to position “Config”
4.)
Choose input mode on extension modules:
Terminals X1/X2 open = open circuit operation
Terminals X1/X2 linked = closed circuit operation
5.)
Set delay on switch, „td“ 0 ... 10 s
6.)
Power up the system
7.)
Fault signal LEDs of the base module are flashing for some time
8.)
On the detected extension modules the fault signal LEDs are now
flashing
9.)
Fault signal LEDs change to continuous state and indicate number
of detected extension modules in binary code
10.) The detected modules are stored no voltage safe in the base
module memory. The fault annunciator only works with the
detected modules. If a new module is added, the configuration
cycle has to be run again.
11.) Select the required alarm function with switch “MODE” on the base
module
12.) Press push buttons QH and QHC to leave the configuration mode.

Lamp Test
Pressing the pushbuttons QH and QCA simultaneously during normal
operation will force a lamp test function (LT). During lamp test all fault signal
LEDs are switched on.
The lamp test function can also be operated by bridging the terminal QX1/
QX2 (connection remote reset) if this function is selected on switch “Set”
for QX1/QX2
Fault Diagnostics
To indicate failures of the system the unit generates a flash code on the Bus
LED. When a failure code 1 to 3 is displayed, the contacts of the common
alarm relay switch off.
LED continuously on:
System has no failure
Failure 1
:
Configuration failure. One ore more
extension modules, that have been
detected during configuration do not exist
anymore. The address of the first missing
extension module is displayed as binary
code on the fault signal LEDs.
Failure 2
:
The base module cannot communicate
with the extension modules. The address
of the first extension module that cannot
communicate with the base module is
displayed as binary code on the fault
signal LEDs.
Failure 3
:
The bus wire is interrupted or the bus is not
terminated correctly. The base module
does not find any extension modules to
communicate with.
Failure 4
:
In normal operation: the configuration data
has been found faulty. A new configuration
cycles has to be run.
During configuration: the detected
configuration data could not be stored.
Failure 5
: New modules unknown to the device
software of the base module have to be
implemented by a firmware update of the
base module.
Remark:
Different types of devices (device classes) can be connected
to the annunciator bus e.g. extension modules RP 5995, display
units EH 5994, EH 5995 etc. The base module detects the
different module types and adds a device specific number to the
adjusted bus module address (address offset). In the case of
failure this added number is indicated as binary code on the
LEDs of the base module.
Max. 4 text display units EH 5996 can be connected to the
Base module RP 5994.
These 4 units has to be designation by adresse 0 up to 3
