OVERVIEW OF VM600
Mk2
MACHINERY PROTECTION SYSTEM (MPS) HARDWARE
2.2.1 MPC4
Mk2
module LEDs
LEDs on the front panel of the MPC4
Mk2
module are used to indicate the status and
behaviour of a VM600
Mk2
MPS (MPC4
Mk2
+IOC4
Mk2
module and any associated RLC16
Mk2
modules).
In general:
• The DIAG/STATUS LED indicates the status and behaviour of the VM600
Mk2
MPS:
• DIAG/STATUS ○ indicates system booting.
• DIAG/STATUS ● indicates system not configured when blinking slowly.
• DIAG/STATUS ● indicates normal system operation.
• DIAG/STATUS ● indicates trip multiply when blinking slowly and alarm bypass
when blinking quickly.
• DIAG/STATUS ● indicates fail safe (that is, the system-wide VM600
Mk2
MPS
safety-line control signal has been activated by the MPC4
Mk2
module).
•The CHn and AXn LEDs indicate the status and behaviour of the dynamic and auxiliary
channels respectively:
•CHn ○ indicates channel not configured.
•CHn ● indicates normal channel operation.
•CHn ● indicates alarm bypass (AB) or sensor/measurement chain problem when on
continuously, an alert alarm (not first out) when blinking slowly and an alert
alarm (first out) when blinking quickly.
•CHn ● indicates a danger alarm (not first out) when blinking slowly and a danger
alarm (first out) when blinking quickly.
• The LOCK LED indicates the status of the VM600
Mk2
MPS:
•LOCK● indicates that the VM600
Mk2
MPS is Locked (safety/secure operating
mode).
•LOCK● indicates that the VM600
Mk2
MPS is Unlocked (maintenance mode).
Table 2-1 provides detailed information on the behaviour of the MPC4
Mk2
LEDs when the
“standard” operating firmware is installed and running on the module.
Table 2-2 provides detailed information on the behaviour of the MPC4
Mk2
LEDs when the
recovery firmware is installed and running on the module.
Figure 2-2 provide some examples of MPC4
Mk2
LED activity for typical VM600
Mk2
MPS
situations.
