5.4.1 Unloader Indicator Block
The SCV-series unloader indicator has been changed to the
new type indicator (right picture) with the protection grade
IP66 by improving the performance of the dust and water proof
from December 2014 Moriya factory production.
This new indicator IND-052WP and IND-062WP are nearly
same to the traditional indicator in the following items: outer
dimensions, mounting method to the compressor, signal
output of the loaded capacity 0 % to 100 % by using a
potentiometer, and contact output function by using
micro-switches.
Major changes (improvements) are described in Table 5-6.
