Pressure Controlled Supply Fan + Esm Fixed Speed - Siemens G120P Technical Manual

7.3 Pressure controlled supply fan + ESM fixed speed

● Macro 105 "Pressure controlled supply fan + ESM
fixed speed"
● Pressure in air duct regulated by integrated PID
controller
● Flying restart and automatic restart activated
● Essential service mode (in the event of fire) with
fixed frequency
● Error message: Digital output 0
● Status display: Digital output 2
When selecting this application using macro 105, the
technological unit remains unchanged at [%]. If
necessary, adapt the unit as described in the parameter
list. Select the values depending on the used sensor.
Notice:
In the case of the extended emergency mode, the
customer can no longer lodge any claims for warranty.
Extended emergency mode and the faults which arise
during this mode are logged in a password-protected
memory and can be read by the repair center.
