The holding (braking) force for dry running or mineraloil wetted shafts is not less than 2 x M, but will not exceed 3,5 x M. 2 Minimum operating pressure is 40 bar. In case a spring base is installed, for releasing without lifting the required pressure is 60 bar, conf. "Technical Information TI-A20“. Admissible working pressure is 250 bar. 3 As supplied port LL is plugged by a plug screw. It may be used alternatively to port L and is usefull for air-bleeding. It is generally recommended to install the Auto-Bleeder as descibed in the "Technical Information TI-Z10“ at port LL (or L respectively). 128 176 Subject to modification without prior notice 4 Hydraulic operating volume. 5 Proximity switch holders are provided for standard proximity switches M12x1 shielded and with a nominal switching distance of 2 mm, except KR 25 and KR 28: M8x1 with nominal distance 1,5 mm. For easier service, the proximity switch holders have a positive stop and are presetted when deliverd from the factory. 6 Port T is used for pressure compensation (breathing). It is plugged with an air filter element. If, however, moisture or aggressive media are present, a hose instead of the filter must be installed to connect the device with a clean atmosphere (e.g. hydraulic tank). SITEMA GmbH & Co.KG .
