Basically it is possible to counteract a higher counter pressure as a shorter discharge period will increase gas production.
perma NOVA is a gas driven lubrication system. The set discharge period is based on lubrication points without counter pressure. The higher the counter pressure, the longer the discharge period. It is important to determine the counter pressure at the lubrication point for a correct function of the lubrication system.
No contact between control- and LC unit. If you are using perma NOVA for the first time, please check if control- and LC unit are screwed together correctly. You may want to unscrew the two parts and try screwing them together again (shift position by 180°). If the display still does not react, then the LC supply battery is most likely defective. Please use a new LC unit (max. storage life is 2 years). If the new LC does not work either, the control unit is defective.
Yes, the discharge period can be changed.
NOTE: A changed discharge period will affect the original exchange date. In this case you must visually keep on checking the piston position to see when the system is empty.
No, compressed air will damage the electronics of the control unit. Once the perma NOVA is assembled, no dirt or dust can get inside. The protection cover can be used to protect the outside of the control unit.
perma NOVA 65 was specially developed for applications that require minimal re-lubricaiton or for applications where confined space allows for the use of a compact lubrication system only.
Inside, where perma NOVA is protected, the mounting position does not matter.
Outside, it should be mounted upright with a protection cover (control unit on top). If upright mounting is not possible, then perma NOVA can also be mounted horizontally or tilted.
Do not mount upside down (control unit on bottom) as over a longer period of time, moisture might get into the lubricator via the connection thread between control and LC unit.
perma NOVA received IP 65 protection. It is dust tight and protected against water jets from all sides. It is not suitable for continuous operation under water.
The display only signalizes correct function of the electronics. It cannot detect gas building problems or leakages. However, every NOVA control unit is tested before it leaves perma-tec and should therefore function correctly.
No. The gas generating process inside the LC unit is hermetically sealed. The produced pressure only affects the lubricant discharge, not the control unit.
During the „Quick Start“ phase, the system temporarily produces more gas. This enables the lubricator to discharge the first lubricant already within the first day (regardless of the selected discharge period and the ambient temperature).
Screw on tight and ensure that one of the raised edges on the control unit lines up with the marking on the LC unit.
It is not necessary to set the LC size for the perma NOVA, as the perma NOVA control unit automatically detects the used LC. All you have to set is the desired discharge period.
To prevent contact interruptions between the electrical components, capacitors have been installed in the control unit. Therefore, when replacing the LC unit, is is essential that the LC display switches off first (max. waiting time 4 sec.) before a new LC unit and the control unit are assembled.
Failure to do so can result in rapid discharge of the LC unit.
If the discharge period is not changed, the previous setting will remain valid. There will be another „Quick Start“. The half filled LC unit will be empty within half of the selected discharge period.
At temperatures below -20 °C, the gas production will stop. The discharge will continue as soon as the temperature reaches -20 °C or higher. Temperatures above +60 °C may permanently damage the lubrication system and its components.
The maximum hose length at normal ambient temperatures (20 °C) is 2 m.
A general answer to this question is not possible. It depends on how the system is used. Some applications put more strain on the system than others.
Before you reuse the control unit, always check:
- Is the desired discharge period setting possible?
- Does the display signal correct operation?
The user should note the activation date and the exchange date on the label.
If the discharge period is changed after the initially programmed discharge period has started, the exchange date on the label is no longer valid. Therefore we also recommend the use of our lubrication- and maintenance plan (free download from our webpage). Changes can be noted there which guarantees optimal control over all lubrication points.
In perma single-point lubrication systems, all greases up to NLGI 2 and all oils can be used.
Lubricants can be ordered directly from the manufacturer by perma or supplied by the customer.
