3.1 Intended use
HV Control Panel is intended for the control and su-
pervision of a high vacuum system with Nederman
FlexFilter, and VAC or RBU vacuum source.
For FlexFilter EX, use the HV Control Panel EX.
3.2 Function
The function of the HV Control Panel is to control
cleaning, and if applicable, emptying Nederman Flex-
Filter and pre separators.
It starts a VAC or RBU using the Star/Delta (Y/D) meth-
od in order to reduce starting motor current. During
the start sequence, the startup valve in the vacuum
unit reduces the motor load. When in Delta (D) mode,
the valve is activated and the unit can supply the sys-
tem.
There are three control modes: Off, Standby, and Run-
ning.
The control panel has also a week timer and an over-
time/timer function.
A Pilot signal (PS) is used in installations with auto-
matic start/stop controlled by microswitches on work
sites (AS-set).
After power-on, the control panel is normally in Off
mode and can be set to Standby mode either by press-
ing the green Start button or remotely.
The control panel enters Standby mode and waits for
a pilot signal. When the pilot signal becomes active,
the control panel goes into Running mode and the
VAC/RBU starts. A test start can be done by pressing
the Test-start button.
When the Pilot Signal becomes deactivated, the SSR
stop delay begins to count down until the VAC/RBU
stops and the HV Control Panel goes into Standby
mode.
When RBU is selected, the DIR idling delay also starts
to count down, the startup valve opens and the RBU
goes into Idling mode.

Description

the main switch is turned off to the
