For models with PWM/ O.C. output:
PM5 = PW
M 50Hz
PM6 = PWM 60Hz
OA7 = two state, it can be used as an
op
en collector output.
For models with [4 to 20mA] or 
[0 to 10V] output:
Cur = 4 to
20mA current output.
tEn
= 0 to 10V voltage output.

activation
delay
0 to 255min
When [i1F = PAL]:
time interval to
calculate the number of the pressure
switch activation.
When [i1F
= EAL or bAL] (external
alarms): d1d parame
ter defines the time
delay between the detection and the
successive signaling of the alarm.
When [i1F
= dor]: this i
s the delay to
activate door open alarm.
