Defines the location of the remote safety.
P3.5.1.51
Remote Safety 8*
DigIN Slot0.2
1824
Defines the location of the remote safety.
P3.5.1.52
Essential Services*
DigIN Slot0.1
1827
Defines the location of the essential service activation signal.
NOTE: Requires EssentServEnable (P3.18.5) to be enabled to
take effect.
P3.5.1.53
Overload
(Accessible when
Bypass (P3.17.4) =
Electronic or
Conventional
DigIN SlotA.5
1825
Defines the location of the bypass overload relay.
NOTE: Is it not recommended to change this value. The overload
relay is factory wired to digital input 5 on all Conventional and
Electronic Bypass options.
*Accessible only when Bypass (P3.17.4) is set to a value of Electronic.
Analog Inputs (M3.5.2)
The analog inputs are very flexible to use. Parameters are functions/features that connect to the required
analog input terminals. The analog inputs are represented by the slot they exist on. Analog inputs 1 and 2 exist
by default on SlotA. For example, AI 1 Signal Selection (P3.5.2.1) would connect analog input 1 when set as
AnIN SlotA.1.
NOTE:
The status of the analog inputs can be monitored in the Multimonitor (M2.1)
view, or in the I/O and Hardware (M5) menu.
The analog inputs settings are presented in the following table:
Table 32: Analog Inputs Settings.

Description
P3.5.2.1
AI1 Signal Sel
AnIN SlotA.1
377
Defines the location of the signal
to be used as analog input 1.
P3.5.2.2
AI1 Filter Time
s

1
378
Defines the time it takes to reach
63% of a step change in the
analog input signal defined by AI1
Signal Sel (P3.5.2.1).
When this parameter is given a
value > 0, the function that filters
out disturbances from the
incoming analog signal is
activated.
NOTE: Long filtering time makes
the regulation response slower.

AI1 Signal Range
0-10V/
0-20 mA
2-10V/
4-20 mA
0-10V/
0-20 mA
379
Defines the signal range for the
analog input defined by AI1
Signal Sel (P3.5.2.1). Ranges are
as follows:
0 = 0 to 10 Vdc/0 to 20 mA
1 = 2 to 10 Vdc 4 to 20 mA
NOTE: This setting can be
bypassed by using AI1 Custom
Min (P3.5.2.4) and AI1 Custom
Max (P3.5.2.5).
