What is a ZENER ‘Application’
An ‘Application’ is firmware that aims to simplify wiring, programming and the commissioning of a Variable
Speed Drive. An ‘Application’ programs the drive and creates new user friendly menus with the essential
settings. This eliminates timely setups, the reading & interpretation of complex manuals and ensures all
critical protection is installed & set up correctly.
Since the ‘Application’ programs all the parameters required and custom ‘User menus’ created there is
generally no reason to program additional parameters unless there is a variation to the intended operation of
this ‘Application’.
Application Summary:
This application provides an advanced PID Pressure Control System (PCS) using an external pressure
transducer. The ZENER 8000 will maintain a constant pressure with changing water consumption
requirements. This is a pressure control system with an automatic turn off function (idle or sleep) when there
is no demand (or flow). An optional ‘No flow switch’ can also be used to trigger idle mode.
A user configured set point provides the pressure for the system to maintain. As the pressure changes the
ZENER 8000 automatically adjusts the speed to ensure constant pressure is maintained.
When demand decreases the drive will reduce in
speed to reduce pressure accordingly. As the flow
& speed reduces the load (current) also reduces.
When the Load reaches the ‘idle threshold’ for the
‘idle delay’ period, the drive goes into idle mode.
In idle mode the PID & output turns off until it is
told to wake. The ZENER 8000 will automatically
wake when the pressure falls to a specified level.
Pumping will recommence and operate in PID
mode.
A flow switch can be used to trigger
idle mode. This simplifies the setup and
provides a better solution with
multiple or a variable set point.
A ‘Pipe Fill’ feature is also available to
run at a set speed during filling then
automatically changeover to PID
mode when the set pressure is
reached.
This also provides protection for the pump &
motor:
i. Motor Overload protection
ii. Output Short Circuit protection
iii. Loss of transducer signal
iv. High & Low pressure Protection
v. Optional Low Bore level protection
