Parameter Name
Description
Alarm Output #2 Setup Parameters
70
Alarm 2 Logical “OR” Activation
Conditions (Flags Table 1)
This Parameter, in conjunction with Parameters 71 & 72, 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. A setting of
zero defeats this “OR” function entirely. Please see the sections “Setting and
Reading Softswitches” and “Setting Alarm Conditions” for further details.
71
Alarm 2 Logical Activation Condition
Inverters (Flags Table 1)
This Parameter, in conjunction with Parameters 70 & 72, defines which
conditions will result in the Alarm 2 output being activated. The function
allows selected Drive Condition Flags to be “inverted” before being presented
to the “inputs” of the “AND” function (see Parameter 72). Please see the
sections “Setting and Reading Softswitches” and “Setting Alarm Conditions”
for further details.
72
Alarm 2 Logical “AND” Activation
Conditions (Flags Table 1)
This Parameter, in conjunction with Parameters 70 & 71, 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. A setting of
zero defeats this “AND” function entirely. Please see the sections “Setting and
Reading Softswitches” and “Setting Alarm Conditions” for further details.

Alarm 2 Output Style & Reset
Configuration
This setting configures the output mode and reset method for the Alarm 2
output.
• Mode 1: Constant & Auto Reset
In this mode, the alarm output will remain active until the alarm condition
ceases to exist. The alarm will automatically reset when the conditions
return to normal.
• Mode 2: Constant & Manual Reset
In this mode, the alarm output will remain active until the alarm is reset
manually. See Parameter 74 for details.
• Mode 3: Pulse & Auto Reset
In this mode, the alarm output will pulse on and off until the alarm condition
ceases to exist. The pulsed modes are commonly used for audible alarms
where a constant output would be considered distracting or awkward. The
alarm will automatically reset when the conditions return to normal.
• Mode 4: Pulse & Manual Reset
In this mode, the alarm output will pulse on and off until the alarm is
reset manually. See Parameter 74 for reset details. The pulsed modes
are commonly used for audible alarms where a constant output would be
considered distracting or awkward.
74
Alarm 2 Reset Configuration
This setting determines which actions will cause an active alarm to be silenced
or reset.
• Mode 1: No Silencing, Reset On ENTER Button Press
In this mode, an active alarm cannot be silenced. Once the alarm condition
ceases to exist, however, the ENTER button may be pressed to cause a
manual reset.
• Mode 2: No Silencing, Reset On S2 Input High (Not Wired To Common)
Similar to Mode 1. Once the alarm condition ceases to exist, setting the S2
input to a high (+5V) state or allowing it to float disconnected will cause a
manual reset.
• Mode 3: No Silencing, Reset On S2 Input Low (Wired To Common)
Similar to Mode 1. Once the alarm condition ceases to exist, setting the
S2 input to a low (COM) state or wiring it to common will cause a manual
reset.
• Mode 4: Silencing Enabled, Reset On ENTER Button Press
When the conditions for an active alarm persist, pressing any user-interface
button will result in the alarm being silenced or deactivated, but not reset. A
second attempt to reset the alarm must be made after the condition ceases
to exist to clear the alarm.
• Mode 5: Silencing Enabled, Reset On S2 Input High (Not Wired To Common)
Similar to Mode 4. Setting the S2 input to a high (+5V) state or allowing it
to float disconnected will cause the alarm to be silenced or reset depending
on the current state of the alarm conditions.
• Mode 6: Silencing Enabled, Reset On S2 Input Low (Wired To Common)
Similar to Mode 4. Setting the S2 input to a low (COM) state or wiring it
to common will cause the alarm to be silenced or reset depending on the
current state of the alarm conditions.
75
Alarm 2 Annunciator Flash On Alarm When set to 1, this will cause the “Alm2” LED Annunciator to flash when an
alarm 2 condition is active. A setting of zero defeats this function.
76
Alarm 2 Pulse on Time
This Parameter defines the number of seconds the output should be enabled
during the ‘on’ phase of an active pulsing alarm’s output.
