Operating Instructions
7.3 Set-up of the limit value switch
The limit value switch has to be configured by the software ISpac Wizard. The following
scheme illustrates different ways to set-up the thresholds of the relay contacts A and B.
The scheme is an example, other set-ups are possible:
Limit value A
Limit value A - Hysteresis
Limit value +Hysteresis
Limit value B
Set-up in the ISpac Wizard:
„closes if value > limit value"
„opens if value > limit value"
„closes if value < limit value"
„opens if value < limit value"
In case of a detected line fault the relays are de-energized means the contacts are open.
7.4 Re-closing lockout function (via configuration software ISpac Wizard)
The re-closing lockout function has to be configured by the software ISpac Wizard. The
relay contact is remaining in the working position (i.e. NO contact remains closed) even if
the process value is returning to value which is below or above the set point. The re-closing
lockout function avoids that the operator miss a detected threshold event.

Description
"deactivate"
Default set-up – function disabled
"active"
Function as described above. The selected operating mode ("open" or "closes" see chapter 7.3.) is
kept even if the trigger is not available. The re-closing lockout function is reset by actuating the DIP
switch LF (ON-OFF-ON or OFF-ON-OFF) or a short disruption of the power supply. In case of a
Version
detected error in parallel the limit value contact turns to the selected alarm state (e.g. "opens if
9162/13-11-12
value > limit value" the contact opens)
"active"
Function as described above. The selected operating mode ("open" or "closes" see chapter 7.3.) is
kept even if the trigger is not available. The re-closing lockout function is reset by actuating the DIP
switch RL (ON-OFF-ON or OFF-ON-OFF) or a short disruption of the power supply. In case of a
Version
detected error in parallel the limit value contact turns to the selected alarm state (e.g. "opens if
9162/13-11-14
value > limit value" the contact opens)
