Different versions of the MPC4 card
MPC4 / IOC4T CARD PAIR
and RLC16) in addition to safety-related machinery protection in the form of safety MPC4
cards.
However, the safety MPC4 card (MPC4SIL) does not support all of the processing modes
supported by the standard and the separate circuits versions of the MPC4 cards (see
Table 7-1). For example, the MPC4 SIL card does not support the speed/phase reference
(tachometer) input channels, the Narrow Band (Tracking) Vibration and S
max
processing
functions, and it does not support the danger bypass (DB), trip multiply (TM) and channel
inhibit functions.
In addition, the use of standard MPC4 cards or safety MPC4 cards in a machinery monitoring
system for a safety-related application requires that the complete system configuration is
manually reviewed in order to:
• Ensure that the VM600 rack configuration is permitted.
• Avoid possible conflict from additional cards.
• Ensure that the MPC4 cards’ configurations are permitted.
NOTE: Refer to the VM600 safety manual for further information.
4.1.4 Identifying different versions of the MPC4 card
The different versions of the MPC4 card can be visually identified from their panels, as the
lower handle on the panel is different.
• For the standard and separate circuits versions of the MPC4 card, the label on the lower
handle of the panel displays the text “MPC 4” against a blue background, as shown in
Figure 4-1 (a).
• For the safety (SIL) version of the MPC4 card, the label on the lower handle of the panel
displays the circular TÜV Nord logo and text “MPC 4” against an orange background, as
shown in Figure 4-1 (b).
The ordering number (PNR) for a MPC4 card is in given in the format 200-510-SSS-xHh.
In this PNR, x represents the version of the MPC4 card as follows:
• 1 indicates the standard version of the card.
• 2 indicates the separate circuits version of the card.
• 3 indicates the safety (SIL) version of the card.
NOTE: Refer to the MPC4 machinery protection card data sheet for further information.
In the VM600 MPSx software (version 2.6.x or later):
• MPC4 is used to refer to the standard and separate circuits versions of the MPC4 card.
• MPC4SIL is used to refer to safety version of the MPC4 card.
NOTE: Refer to the relevant manual for further information: VM600 MPS1 software
manual or VM600 MPS2 software manual.
