Rotational Speed Monitor
1GB ROTATIONAL SPEED MONITOR
!This product Information contains general information about the dual channel
speed/ key monitor types A6312/06 & A6312/08. If not stated otherwise, all
information denoted by A6312 is valid for both types, listed before.
The two−channel rotational speed monitor A6312 is a module of the A6000 machine monitoring
system. The micro−processor controlled monitor is used in conjunction with two eddy current
measuring chains or hall−effect sensors (e.g. PR 9376) and in combination with triggering
wheels to measure and conditioning of shaft speeds and rotational reference marks
(key−pulses).
Both channels may be used separately used to measure:
•2 speeds from 2 shafts
•2 key−pulses from 2 shafts each with a triggermark (with phase relation)
Both channels may also be used in combination with each other:
•to detect the direction of rotation of one shaft
•to detect a difference between two shaft speeds
i
In this product information the mounting and electrical connection of the
monitor is described.
For secure use of the monitor, observe the direction for use “Rotational Speed
Monitor A6312” (order number: 6110−90025). You can find this direction on
the configuration software CD as pdf−data file. Amongst others, it contains
useful informations for configuration and use of the A6312.
To ensure the safe operation of the monitor and to permit setting of all
functions, it is indispensable to use only the latest versions of configuration
software (version 2.05 or newer) and operating manual.
The use of old operating manuals or configuration programs out of date may
lead to malfunctions or limitations of the measuring functions.
1.1 Scope of Delivery
The following parts are included in the scope of delivery and must be contained in the shipment:
•Rotational Speed Monitor A6312
•This product information
Accessories (not included in delivery):
•MMS ParaKit (order no.: 9510−00027)

1.2 CSA Certification
STOP
For valid CSA certification, all devices (IMR 6000/xx and A6000 modules)
must be marked with the respective CSA lable.
If no CSA lable is available on the respective device, this device is not CSA
certified!
The respective CSA lable looks as shown in the following picture.
1.3 CSA −Conditions of acceptability
This device must be supplied with safety low voltage SELV LPS (C22.2 60950−1) 24V. The
voltage required for operation must be drawn from a separate power supply.
The IMR system should be placed in a suitable fire enclosure.
The IMR system is evaluated for an ambient of 0°C to 45°C.
Adequate ventilation space has to be provided so that heat does not build up. The ventilation
space must be at least 1 RU (13/4 inch) in all directions. If the ambient temperature of the rack
rises above 45 °C, cool this instrument with a forced air fan, cooler, or similar.
When mounting several IMR units above each other in one cabinet, install cooling fan racks in
between instead of the ventilation space. The necessary specifications for cooling fan racks
result from the environmental and sitting criterions of the cabinet and thus cannot be defined
generally.
1.4 Advice for Installation
STOP
According to the IEC 61010 directive, permanently installed systems must be
equipped with a power disconnect device (e.g. a switch or circuit−breaker
according to IEC60947−1 and IEC60947−3). When using an IMR rack, in
compliance with this directive, such a switch or breaker must be implemented
into the cabinet installation and easily accessible for the user. Furthermore,
each disconnect devices must be labeled in accordance to the associated
system.
1.5 Installation and Mounting
A prepared 3U slot in a 19” rack, or other Intermas−compatible enclosure, is required for
mounting the A6312 monitor. The slot must be fitted with a 48−pin plug connector (DIN 41612,
design F 48 M). The pin assignment is listed in the following table.

Jumper RS 485
RS 485 bus operation requires an electrical terminator on the first and last bus device.
This is done with plug−in jumpers, that are on the controller board. The figure shows the position
of the jumpers.
To activate the bus terminator and to place lines “A” and “B” on the references, plug the jumpers
as shown in Fig. b). Fig. a) shows the jumper position for deactivated bus termination and open
references (delivery status).
•Plug−in jumper 1−2 closed: Bus line “B” via pull−down resistor on ground
•Plug−in jumper 3−4 closed: 120 ΩResistor between “A” and “B”

Der zweikanalige Key−Monitor A6312 ist eine Baugruppe des A6000 Maschinenüberwa-
chungssystems. Der mikrocontrollergesteuerte Monitor dient in Verbindung mit zwei Wirbel-
strommessketten oder Feldplattenaufnehmer (z. B. PR 9376) der Messung und Aufbereitung
von Wellendrehzahlen oder Drehbezugssignalen (Key−Signalen) an Turbinen aller Art,
Kompressoren, Lüftern, Getrieben usw.
Die beiden Kanäle des Monitors arbeiten unabhängig voneinander. Mittels Konfiguration
können folgende Messungen eingestellt werden:
•Drehzahlmessung an zwei Wellen.
•Key−Messung an zwei Wellen.
Durch Kombination der beiden Kanäle können folgende Messungen eingestellt werden:
•Drehrichtungserkennung an einer Welle.
•Berechnung der Drehzahldifferenz zweier Wellen.
Die Messsignale werden pro Kanal über einen Open−Kollektor−Ausgang, TTL−Impuls−
Ausgang und Stromausgang zur Verfügung gestellt.

In dieser Produktinformation wird die Montage und der elektrische Anschluss
des Monitors beschrieben.
Für den sicheren Betrieb des Monitors muss die Gebrauchsanleitung
“Drehzahl−/ Key−Monitor A6312” (Bestellnr. 6100−90025) unbedingt
beachtet werden. Die Gebrauchsanleitung befindet sich im pdf−Format auf
der CD mit der Konfigurationssoftware. Sie enthält unter anderem
Informationen zur Konfiguration und Bedienung des A6312.
Um den sicheren Betrieb des Monitors zu gewährleisten und um alle
Funktionen des Gerätes einstellen zu können ist es erforderlich, die jeweils
aktuellsten Versionen von Konfigurationssoftware (ab Version 2.05) und
Gebrauchsanleitung zu verwenden.
Die Verwendung älterer Konfigurationsprogramme oder Gebrauchs−
anleitungen kann Funktionseinschränkungen oder Fehlfunktionen zur Folge
haben.

2.2 CSA Zertifizierung
STOP
Zur gültigen CSA Zertifizierung müssen alle Geräte (IMR 6000/xx und A6000)
mit einem entsprechenden CSA Label versehen worden sein.
Für den Fall das kein CSA Lable auf dem Gerät angebracht wurde ist dieses
Gerät nicht CSA zugelassen!
Das entspechende CSA Label sieht wie nachfolgend dargestellt aus.
2.3 CSA −Akzeptanzkriterien
Dieses Gerät muss mit Schutzkleinspannung SELV LPS (C22.2 60950−1) 24V betrieben
werden. Diese Betriebsspannung muss von einem seperaten Speisegerät bezogen werden.
Das IMR−System sollte in einem zweckmäßigen Feuerschutzgehäuse installiert werden.
Das IMR−System ist bewertet für einen Umgebungstemperaturbereich von 0°C bis 45°C.
Es muss angemessener Zirkulationsfreiraum vorgesehen werden damit sich keine Hitze
aufstauen kann. Der Zirkulationsfreiraum muss mindestens 1 HE (13/4 inch) in allen Richtungen
betragen. Für den Fall das die Umgebungstemperatur des Racks über 45°C steigt müssen die
gerätschaften mit einem festen Lüfter, einer Kühlvorrichtung etc. auf den entsprechend
zugelassenen Temperaturbereich heruntergekühlt werden.
Werden mehrere 19” Rahmen übereinander in einem Schaltschrank installiert so sollten
anstelle des Zirkulationsfreiraum entsprechende 1HE Lüftereinschübe installiert werden. Da die
notwendigen Spezifikationen derartiger Lüfter aus den Umgebungs−und Standortbedingungen
des Schaltschrankes resultieren können keine generellen Lüfterspezifikationen festgelegt
werden.
