I have jandy Aquapure saltwater chlorine generator with PDA control. Suddenly under eqiupment status on remote PDA secreen the salwater chlorine generator readings are not showing up altough other pool eqiupment reading is still showing up. On aqualink control panel box outside the green light under cell and flow is on and the panel says chlorine production 55% but no chlorine percentage or salt ppm reading showing up on PDA remote secreen.
