This parameter is used in order to display the span velocity
corresponding to PV_SCALE. E100.
This parameter selects the units for density as required when
making settings using MASS_FLOW_DENSITY.
Setting of the density for mass-flow rate. This parameter is
necessary in situations where t, kg, klb or lb has been selected
as the mass unit in PRIMARY_VALUE_RANGE. If a mass unit is
selected in PRIMARY_VALUE_RANGE and a value of 0 is set
for this parameter, the setting alarm "57: Density SetErr."
will be displayed. In this case, ensure that density is set correctly.
Indicate the value of limit switch 1, which switches ON and OFF
depending on the digital value of the target input parameter
selected in LIMSW_1_TARGET and based on the threshold set
in LIMSW_1_SETPOINT with the hysteresis set in
LIMSW_1_HYSTERESIS. The direction of the switching action
determined by the setting in LIMSW_1_ACT_DIRECTION.
The target of limit switch 1.
Sets the threshold of limitswitch 1. If the value of
LIMSW_1_ACT_DIRECTION is HIGH LIMIT, limit switch 1 turns
ON when LIMSW_1_TARGET has gone beyond
LIMSW_1_SETPOINT. If the value of LIMSW_1_ACT_DIRECTION
is LO LIMIT, limit switch 1 turns ON when LIMSW_1_TARGET
has gone below LIMSW_1_SETPOINT. The unit set in
LIMSW_1_UNIT applies.
Selects the direction of the limit switch 1's actions:
1: LO LIMIT (Low-limit switch)
2: HIGH LIMIT (high-limit switch)
Sets the hysteresis of limit switch 1 to be applied for resetting
the LIMSW_1_VALUE_D to OFF after LIMSW_1_TARGET went
beyond LIMSW_1_SETPOINT and LIMSW_1_VALUE_D turned
ON (when used as a high-limit switch), or after LIMSW_1_TARGET
went below LIMSW_1_SETPOINT and LIMSW_1_VALUE_D
turned ON (when used as a low-limit switch).
Indicate the unit set in LIMSW_1_TARGET.
Indicate the value of limit switch 2, which switches ON and OFF
depending on the digital value of the target input parameter
selected in LIMSW_2_TARGET and based on the threshold set
in LIMSW_2_SETPOINT with the hysteresis set in
LIMSW_2_HYSTERESIS. The direction of the switching action
determined by the setting in LIMSW_2_ACT_DIRECTION.
The target of limit switch 2.
Sets the threshold of limitswitch 2. If the value of
LIMSW_2_ACT_DIRECTION is HIGH LIMIT, limit switch 2 turns
ON when LIMSW_2_TARGET has gone beyond
LIMSW_2_SETPOINT. If the value of
LIMSW_2_ACT_DIRECTION is LO LIMIT, limit switch 2 turns
ON when LIMSW_2_TARGET has gone below
LIMSW_2_SETPOINT. The unit set in LIMSW_2_UNIT applies.
Selects the direction of the limit switch 2's actions:
1: LO LIMIT (Low-limit switch)
2: HIGH LIMIT (high-limit switch)
Sets the hysteresis of limit switch 2 to be applied for resetting
the LIMSW_2_VALUE_D to OFF after LIMSW_2_TARGET went
beyond LIMSW_2_SETPOINT and LIMSW_2_VALUE_D turned
ON (when used as a high-limit switch), or after LIMSW_2_TARGET
went below LIMSW_2_SETPOINT and LIMS
W_2_VALUE_D turned ON (when used as a low-limit switch).
