9.1
Replacement of the device
• If replacing by a device with identical design, readjust the DIP switch, if necessary.

Parameterizations
9.2.1 Adjustments of limiting values for relay
• Configure the limiting value function using the ISpac Wizard software.
The following representation shows possible adjustments of the limit contacts
for relays A and B.This is an example, other assignments are possible.

If a line fault is detected, the limit value relays drop out (for exception refer to chapter
"Anti-pumping device").
9.2.2 Anti-pumping device
If a limiting value is reached, the anti-pumping device ensures that the limit contact
remains in working position ("OFF") even if the process variable that caused the reaction
is no longer valid. This function is used to detect whether the value exceeds or falls below
the specified limiting values.
• The anti-pumping device can only be activated by using the ISpac Wizard software
(independent of switch position RL).
• The anti-pumping device is reset using the DIP switch "RL" (or via ISPac Wizard or
power reset).
Resetting using the DIP switch "RL" is also permitted during operation in
Zone 2 and with connected intrinsically safe input signals.

Set-up in the ISpac Wizard:
„opens if value > limit value“
„opens if value < limit value“
Limit value A
Limit value A - Hysteresis
Limit value B +Hysteresis
Limit value B
