Special switching values agreed between SGB and customer
The following abbreviations are used in the table:
P
TS
maximum pressure at the low point of the tank, including overlay pressure
p
AE
switch value "Alarm ON", the alarm is triggered at the latest at this pressure
p
AA
switch value "Alarm OFF", the alarm goes off on passing this value.
The switching value "Alarm OFF" is approx. 15 mbar higher than the switch value
"Alarm ON" for pressure stages < 1000 and approx. 100 mbar higher for pressure stages
> 1000
(p
AA
= p
AE
+ ~15 mbar (pressure stages < 1000) ~ 100 mbar (pressure stages > 1000))
p
PA
Switch value "Pump OFF" (=nominal pressure)
p
PE
Switch value "Pump ON“
The switch value "Refill ON" is approx. 15 mbar lower than the switch value "Refill OFF"
for pressure stages < 1000 and approx. 100 mbar lower for pressure stages > 1000
(p
PE
= p
PA
- ~15 mbar (pressure stages < 1000) ~ 100 mbar (pressure stages > 1000))
p
ÜDV1
Opening pressure overpressure valve 1 (interstitial space side)
p
PRÜF
Minimum test pressure of the interstitial space
1
The table states the opening pressure for the overpressure valve at which the volume flow of the pump is blown off.
The triggering pressure (first opening) is lower.
