2. PRODUCT FEATURES
VIP5 Plus offers many functions, the following brief summary are:
•
Integrated LCD Display for diagnostic and ease of use;
•
Diagnostic and Lubricant Counters for Operation and Alarm conditions;
•
Three separate inputs (to monitor Dual line pressure switches, progressive cycle switch, injector pressure switch and
external signals to use as a counter for standby or lubrication phase );
•
Signal Inputs can be NPN, PNP or a Clean Contact (or Namur style switching);
•
Time or counter based determination of both Lubrication and Standby Phase;
•
Counter based Lubrication phase can be used independently while monitoring correct function of a cycle switch,
ideal for use in impulse piloted system (e.g. chain and conveyor lubrication);
•
Ability to configure pump output for Electrical or pneumatic pump (pump On/Pump Off values can be set
individually);
•
General Alarm Output Relay can be a constant signal or generate a coded alarm to allow remote PLC to determine
nature of alarm;
•
Monitoring and indication of the thermal protection trip input;
•
Minimum Level Input;
•
4..20mA Input for analogue measurement of Reservoir Level;
•
Maximum level monitoring;
•
Separate remote output signalling for Minimum Level alarm and General Alarm conditions;
•
4-20 mA continuous input level monitoring;
•
Ability to control line invertor valves for dual line systems with pneumatic or electromagnetic actuators;
•
Ability to power input and output circuits using different power sources;
•
Ability to isolate the voltage of the inverter valve power circuit from the main power framework.
All configuration parameters can be set from the Setup menu via the LCD display using the front panel keys. No complex
internal switches need to be set.
3. DESCRIPTION OF OPERATING PROCEDURES
The
VIP5
controller has three operating modes:
1.
CYCLE
2.
PULSE
3.
FLOW
CYCLE and PULSE
modes are designed for intermittent or continuous lubrication system that requires the control of a pump
and monitoring of feedback signals to determine when lubrication has successfully completed.
FLOW
is designed as a monitoring only operating mode that allows the user to monitor a pulse signal and determine the
actual flow rate. This is useful for process control and generally used in re-circulating systems.
3.1 CYCLE and PULSE Control System operating Principles.
The VIP5 control system is designed to control intermittent or continuous lubrication system with a variety of control
inputs. Intermittent operating principle is based on three distinct phases.
PRELUBE Phase -> Pre Lubrication that occurs during power up of a system.
LUBRICATION Phase (Lube –> Wait stages)
-> This is when lubricant is provided (as above)
STANDBY Phase -> The system is inactive awaiting for the next LUBRICATION PHASE
