GA ramp issue

With the below resident script I'm getting the correct actions with GA '0,56,5' ramping up over 17 minutes and down over 5 minutes but when level is at 255 and the script runs again it resets level to 255 over another 17minutes and the level sits in a looped state neither "on" or "off".and the level is unreadable.
How do I get it to not loop but still reset the ramp up if level is anything other than true "less than 255"

Code:

SOC= GetCBusMeasurement( 0, 50, 48)

discharge = GetCBusMeasurement( 0, 50, 50)

level = GetCBusLevel(0, 56, 5)

if  ( SOC>92) and ( discharge<300)
        then

                -- Set '0/56/5' to "ON" over 17 minutes
                        SetCBusLevel(0, 56, 5, 255, 1020)

log (SOC,discharge,level, state)
 
                                    elseif ( SOC<90) or ( discharge>1000)
                                        then
 
                                                -- Set '0/56/5' to "OFF" over 5 minutes
                                                        SetCBusLevel(0, 56, 5, 0, 300)

log (SOC,discharge,level)
 
end

 

I think I've sorted it out.

Code:

SOC= GetCBusMeasurement( 0, 50, 48)

discharge = GetCBusMeasurement( 0, 50, 50)

level = GetCBusLevel(0, 56, 5)

-- Get state of application 56 group 1 on the local network
state = GetCBusState(0, 56, 5)


if  ( SOC>92) and ( discharge<300) and (level<250)


        then

                -- Set '0/56/5' to "ON" over 17 minutes
                        SetCBusLevel(0, 56, 5, 255, 1020)

log (SOC,discharge,level, state)
 
                                    elseif ( SOC<90) or ( discharge>1000)
                                        then
 
                                                -- Set '0/56/5' to "OFF" over 5 minutes
                                                        SetCBusLevel(0, 56, 5, 0, 300)

log (SOC,discharge,level, state)
 
end
