proportional valves with integral electronics are factory preset with default parameter and ready to use after piping
and electrical connections.
Play with parameters is optional, not mandatory!
Valve vibration or noise
• presence of air in the solenoid; perform air bleeding procedure – see
S
TEP 3
The valve does not follow the reference signal
• valve is powered off, verify presence of 24 Vdc power supply
• valve is disabled, verify presence of 24 Vdc on enable pin - only for /Q and /Z options
• the mechanical pressure limiter interferes with the regulation (only LIRZO, LICZO, LIMZO sizes 16, 25, 32 and /P option) –
check the pressure limiter setting
• poppet sticking – contact Atos service center
Software parameters modifications are lost when valve is switched off
• parameter store operation was not performed, check store procedure – see
S
TEP 4, section 4.3
Software parameters modifications have no effect on the valve
• valve is OFF LINE, check connection procedure – see
S
TEP 4, section 4.1
After the modification of valve parameters, the valve doesn't match the desired behavior
• restore factory default settings pressing ‘Restore Factory’ button, located in ‘Driver - Memory

tore’ window:
- during restore, the current to the solenoid(s) will be temporarily switched off!
- factory parameters will be applied at next driver restart or after power off-on sequence!

RAMPS
Bias setting:
supply the input signal qual to 0%
•
relief valves:
increase the Bias until the pressure starts to increase, then lightly reduce the Bias just to bring back the
pressure lightly over the minimum regulated value
•
reducing valves:
increase the Bias until is reached the minimum desired value of starting pressure
Scale setting:
supply the max input signal; adjust the
S
cale to obtain the max regulated pressure
BIAS AND SCALE
Ramps setting:
select the required ramp configuration and adjust the ramp time to optimize the pressure response accor-
ding to the system characteristics

• lower frequencies reduce the hysteresis of the valve, too low values can affect the valve stability
• higher frequencies increase regulation stability, but increase also the hysteresis of the valve
