Low and high temperatures can influence the selected discharge period. Deviations can either be calculated manually by using temperature factors, or automatically by using the free perma SELECT software.
If temperature rises above +40 °C (+68 °F) discharge period can not exceed 6 months to ensure that system discharges until completely empty.
Remove rotary switch with a screw driver. Then take out and recycle the battery. Dispose empty housing with other oil containing waste.
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period is changed after the initially programmed discharge period has started, the exchange date on the label is no longer valid.
perma FLEX is designed to match the programmed discharge period when there is no counter pressure at the lube-point. The higher the counter pressure (caused by tight lube channels or long tube connections), the longer the discharge period. To ensure proper operation, we recommend to measure the counter pressure at the lube-point.
Basically it is possible to counteract a higher counter pressure by selecting a shorter discharge period (a shorter discharge period will increase gas production).
Low temperatures = slower discharge
Higher temperatures = faster discharge
Important: If the ambient temperature permanently exceeds + 40°C / 140 °F, the selected discharge period must not be longer than 6 months.
perma FLEX starts discharging with a delay because it takes a while to generate the required discharge pressure. The delay depends on several factors such as ambient temperature, selected discharge period and type of lubricant.
Example:
- Ambient temp. +20 °C / setting 6 months / grease SF01: Delay approx. 1 week
- Ambient temp. -20 °C / setting 6 months / grease SF01: Delay approx. 2 weeks
The delay can be shortened by setting the discharge period on 1 month for one day (faster pressure build-up). Sufficient pre-lubrication will also compensate the discharge delay.
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.
