Parameters 275
81.11 AI out hi level Pressure limit for primary outlet pressure supervision. See
parameter 81.09 Outlet prot ctrl.
0.00 … 32767.00
bar
Pressure limit. 100 = 1 bar
81.12 Very high ctrl Enables the secondary supervision of pump outlet pressure
and selects the action taken when very high outlet pressure
is detected. The selected action is taken only after the
measured pressure has remained above the pressure limit
(81.13 AI out very high) for longer than the value of
parameter 81.15 Outlet ctr dly. See the diagram at
parameter 81.09 Outlet prot ctrl.
Note: With a pressure switch, this parameter has no effect.
Not sel Secondary outlet pressure supervision not used. 0
Fault Detection of very high outlet pressure trips the drive. 1
Stop Detection of very high outlet pressure stops the drive. The
drive will restart if the pressure falls below the limit.

81.13 AI out very high Pressure limit for secondary outlet pressure supervision.
See parameter 81.12 Very high ctrl.
0.00 … 32767.00
bar
Pressure limit. 100 = 1 bar
81.14 DI status outlet Selects the digital input for connection of a pressure switch
at the pump outlet. The “normal” state is 1. If the selected
input switches to 0, the action defined by parameter 81.09
Outlet prot ctrl is taken after the delay set by parameter
81.15 Outlet ctr dly expires.
Not used No pressure switch connected. 1074070017

DI2 Digital input DI2 (as indicated by 02.01 DI status, bit 1). 1073807873
DI3 Digital input DI3 (as indicated by 02.01 DI status, bit 2). 1073873409
DI4 Digital input DI4 (as indicated by 02.01 DI status, bit 3). 1073938945
