following values must be set manually (the two limit sensors L2 and L3 not occupied by the
P500 module are always configured manually):
Parameter
Meaning
Lx_DevVar
Selection of monitored process value (the process value must be transferred cyclically
as a 4 to 20 mA signal or HART auxiliary variable)
If
Lx_DevVar
= "NotUsed" is selected, the enables for this limiter (
Lx_AH/WH/WL/
AL_En
) are set to FALSE, and a message is not generated.
Lx_Unit
Unit of monitored process value
Lx_AH/WH/WL/AL_En
Enable monitoring of alarm limit
Lx_AH/WH/WL/AL_MsgEn
Enable message on violation of alarm limit
The
Lx_AlmAct
,
Lx_MonAct
and
Lx_MonTrig
inputs contain the message information read
out of the module and are insignificant if the message configuration is not read out of the
module.
You can monitor the process values (
PV_In
(4 to 20 mA signal),
SV
,
TV
,
QV
) for the following
high and low alarm and warning limits:
●
L1/2/3_AH_Lim
: Limit for high alarm
●
L1/2/3_AL_Lim
: Limit for low alarm
●
L1/2/3_Hyst:
Hysteresis
●
L1/2/3_RespT:
Response time
●
L1/2/3_WH_Lim
: Limit for high warning
●
L1/2/3_WL_Lim
: Limit for low warning
The result of limit monitoring is returned at the interconnectable output parameters:
●
L1/2/3_AH_Act
= 1: Limit for high alarm reached or exceeded
●
L1/2/3_AL_Act
= 1: Limit for low alarm reached or undershot
●
L1/2/3_WH_Act
= 1: Limit for high warning reached or exceeded
●
L1/2/3_WL_Act
= 1: Limit for low warning reached or undershot
Monitoring is always enabled using the input parameters:
●
L1/2/3_AH_En
= 1: Monitoring of the high alarm limits
●
L1/2/3_AL_En
= 1: Monitoring of the low alarm limits
●
L1/2/3_WH_En
= 1: Monitoring of the high warning limits
●
L1/2/3_WL_En
= 1: Monitoring of the low warning limits
The corresponding message is suppressed using the parameters:
●
L1/2/3_AH_MsgEn
= 0: Alarm (high) messages are suppressed
●
L1/2/3_AL_MsgEn
= 0: Alarm (low) messages are suppressed
●
L1/2/3_WH_MsgEn
= 0: Warning (high) messages are suppressed
●
L1/2/3_WL_MsgEn
= 0: Warning (low) messages are suppressed
