Alarm 2 Lower Limit
This setting defines either the lower limit or the lower end of a range for
the alarm region. Alarm limits are set in engineering units without regard
to decimal point or colon position. In Rate and Follower Modes, a limit
of 123 could represent a display value of 123, 12.3, 1.23, or 0.123. When
in Time Mode, a limit of 123 would represent 1:23 on the display.
80
Alarm 2 Upper Limit
This setting defines either the upper limit or the upper end of a range for
the alarm region. Alarm limits are set in engineering units without regard
to decimal point or colon position. In Rate and Follower Modes, a limit
of 123 could represent a display value of 123, 12.3, 1.23, or 0.123. When
in Time Mode, a limit of 123 would represent 1:23 on the display.
81
Alarm 2 Output
Routing
This setting allows the GSD8 to control the “Alarm 1” output of a
selected Modbus “Slot”, provided of course that there is a Modbus card
that supports this function installed in the selected slot. The valid values
for this Parameter are:
• Mode 1: Not Used
• Mode 2: Route Alarm 2 Output to Modbus Slot 100 Alarm 1 Output
In this mode, the GSD8 Alarm 2 output will directly control the Alarm
1 output of a Modbus Card installed in Slot 100, if that card supports
this feature.
• Mode 3: Route Alarm 2 Output to Modbus Slot 200 Alarm 1 Output
In this mode, the GSD8 Alarm 2 output will directly control the Alarm
1 output of a Modbus Card installed in Slot 200, if that card supports
this feature.
• Mode 4:Route Alarm 2 Output to Modbus Slot 500 Alarm 1 Output
In this mode, the GSD8 Alarm 2 output will directly control the Alarm
1 output of a Modbus Card installed in Slot 500, if that card supports
this feature.
85
Alarm 2 Logical “OR”
Activation Conditions
(Flags Table 2)
This Parameter, in conjunction with Parameters 86 & 87, defines which
conditions will result in the Alarm 2 output being activated. The function
is that of a Logical “OR”ing of the selected Drive Condition Flags Table
2. A setting of zero defeats this “OR” function entirely. Please see
the sections “Setting and Reading Softswitches” and “Setting Alarm
Conditions” for further details.
86
Alarm 2 Logical
Activation Condition
Inverters (Flags Table
2)
This Parameter, in conjunction with Parameters 85 & 87, defines which
conditions will result in the Alarm 2 output being activated. The function
allows selected Drive Condition Flags Table 2 to be “inverted” before
being presented to the “inputs” of the “AND” function (see Parameter
87). Please see the sections “Setting and Reading Softswitches” and
“Setting Alarm Conditions” for further details.
87
Alarm 2 Logical
“AND” Activation
Conditions (Flags
Table 2)
This Parameter, in conjunction with Parameters 85 & 86, defines which
conditions will result in the Alarm 2 output being activated. The function
is that of a Logical “AND”ing of the selected Drive Condition Flags
Table 2. A setting of zero defeats this “AND” function entirely. Please
see the sections “Setting and Reading Softswitches” and “Setting Alarm
Conditions” for further details.
Parameter Memory Command Parameters
Rather than being a “setting” or a “switch” type Parameter, Parameters 95 through 99 are used to trigger a
certain “Action” or “Script” that generally performs some Utility function for the GSD8, and/or a Modbus card
installed in the drive. The “value” settings are used as a kind of “key” to make sure these functions are not
accidentally “triggered”.
95
Factory Default Drive
Command
When set to a value of 5, and then pressing the ENTER button, the
GSD8 (Drive only) will be reset to factory default settings. THIS ACTION
CANNOT BE UNDONE! This Command can also be achieved by applying
power to the unit with both the Enter and Down buttons depressed. The
programming jumper must be in the “On” position for this Command to
function. Any Modbus card settings are unaffected.
