Additionally, the VIP5 Control system can also be used as a simple monitoring device in the “FLOW” operating Mode
described later in this manual.
3.1.1 PRELUBE Phase
The user can specify the number of lubrication cycles up to a maximum of 250.
If Prelube is set to zero, the VIP5 controller will not perform any pre-lubrication; in this case if the START parameter setting
is "Resume", when the system is turned on it will revert to its pre-power down, or it will start from a lubrication cycle if the
setting of the start is "Lube".
When Prelube is set greater than zero, pre-lubrication will start in the following cases:
-
When the VIP5 Plus system is powered on;
-
After the RESET button is pressed;
-
After the VIP5 exists from the SETUP menu.
3.1.2 LUBE (Lubrication) Phase
The Lubrication Phase is a set of Lubrication Cycles that can be repeated up to 250 times.
A Lubrication
Cycle
consists of activating the lubrication pump, then
Control
monitoring a feedback signal from a sensing
device if installed. There is then
Delay
period before switching off the pump, and a
Wait
period before the lubrication cycle
can be repeated. Specifically:
-
Cycle
(time) determine how long to wait for the control signal before determining an alarm condition.
-
Control
(Type) determines what kind of control signal (Single Line, Dual Line, Injectors). Alternatively a Timer only
setting means no monitoring will occur.
-
Delay
(time): Is how long to wait for the signal to be confirmed and switch off the pump (in Pressure switch
applications).
-
Wait
(time): determines how long to wait in a pump off condition before repeating the cycle. This is necessary in
injector systems and represents the minimum time required for the injectors to reset. In progressive systems for
example this can be set to zero.
3.1.3 STANDBY Phase
During the
Standby
the VIP5 switches off the pump and waits for the start of another
Lubrication Phase
. The duration of
the
Standby
phase can be determined by a countdown timer or a by an external pulse signal that can be used as a counter.
The VIP5 also allows a combination of both timer and external pulse signals to determine either the next Lubrication phase
or to signal an alarm if external pulse signals are not received within a pre-set time.
3.2 FLOW MODE OPERATING PRINCIPLES
The VIP5 can also be used as a simple Flow monitoring system. When
Flow
mode is selected the unit operates as a flow
display and monitors an external signal to calculate the flow based on external impulses. The User can additionally set a
minimum and maximum Flow limit. If the flow is out of these limits, the remote alarm contact and the alarm LED on the
front panel are both activated.
