2 Safety Information
This manual is a part of the product. Read the manual carefully before using the product and keep it
accessible for future use.
2.1 Intended use
The VC-8000 is a rack-based continuous machinery monitoring platform designed to fully comply with
American Petroleum Institute Standard 670 for machinery protection systems. The system measures
and alarms on a wide variety of vibration, position, speed, temperature, and process variable inputs.
Please see the data sheet (product specifications) for approved sensor types, as well as power
specification - provided to each sensor type.
2.2 Sources of Danger
When installing or maintaining the VC-8000 live parts are a potential source of danger that can lead to
serious, irreversible personal damage or death.
2.2.1 Supply Voltage
The VC-8000 is powered by +24Vdc. However, voltages powering external power supplies can be
much higher; 110/220 Vac, or 90-250 Vdc (for example).
2.2.2 Relay/Trip Voltage
The VC-8000 contains relay (trips) which are connected to third party systems. These trip circuits may
contain high voltages which remain present event when the power to the VC-8000 has been turned
off.
Always use safe practices and test relay connections with a multi-meter to verify if external voltages
are present.
Figure 2-1) High voltage present on relays
Higher contact potentials cause current levels which are extremely dangerous and can
lead to injury or even death!
The permissible levels of contact potentials are:
• Max. 50 Volts in the case of AC voltages.
