The two switch outputs are configured by four parameters respectively.
For the switch point 1 these are
• SP1 On
• SP1 Off
• SP1 Delay
• SP1 Function
Accordingly for switch point 2:
• SP2 On
• SP2 Off
• SP2 Delay
• SP2 Function
The function of the individual parameters is explained for both switch points us-
ing Switch point 1 as an example.
SP1 On defines the activation point, SP1 Off the deactivation point of switch
output 1. The values are shown in the valid unit and set accordingly. The values
are shown in the valid unit and set accordingly. Both parameters can be set in-
dependently over the entire value range.
The value range ranges from MRS – 50% to MRE + 50%. MRS stands for
measuring range start and MRE for measuring range end.
Example: Measurement range = 0 … 100 Pa
The value range for this measuring range is -50 Pa … +150 Pa.
Together, the two parameters SP1 On and SP1 Off determine the switch func-
tion of switch output 1:
• If SP1 On > SP1 Off , the output switches on, if the measured value ex-
ceeds SP1 On. It is only switched off again if the measured value SP1 Off is
undercut (hysteresis function).
• If SP1 On = SP1 Off , the output switches on if the measured value exceeds
SP1 On and off if the measured value undercuts the same value (SP1 Off).
• If SP1 On < SP1 Off , the output switches on, if the measured value lies
within these switch points: i.e:
SP1 On < Measured value < SP1 Off (window function).
SP1 Delay allows the reaction of the switch output to be delayed by between 0
and 1800 s. This parameter applies equally for switching on and off.
SP1 Function changes the function of the switch output 1. It is possible here to
define whether the contact should work as a open contact (NO) or a break con-
tact (NC).
