12.1.4 Setting Event Masks with the Terminal
The event masks can be customized via a terminal. The command SPT4?<ENTER> displays all faults
and alarms, along with their associated event masks. A plus sign (+) means that particular event
mask is enabled, while a minus sign (-) means that mask is disabled.
Refer to 11.1 - Event Mask on page 71 for more information on event masks and their associated
flags.
Unlike the System and User Settings, mask values are set by designated letters, not hex values.
However, as with other RS-232 interface settings, four parameters are passed. See 12.1.2 -
Configuring the Liebert STS2 via the Terminal on page 78 for more details about the
parameters.
The syntax for configuring event masks is:
SPT 4 ID ±D±L±S±E±A
• SPT — is the terminal command used to configure setpoints.
• 4 — setting (group parameter) for event masks, under System Settings.
•ID — event ID. The ID is the item parameter for this command. The ID numbers for each event
are listed with the events in Table 8 on page 74.
• D,L,S,E,A — the event masks: Dial, Latch, Summary, Event log, and Audible. The masks are the
value parameter for the command.
Each mask type must be preceded by a plus sign (+) to enable it, or a minus sign (-) to disable it.
Only the mask that is passed (enabled) is applied when the event occurs.
Note that the Summary and Event Log event masks are only configurable for the LED units.
To set the event masks for a particular event:
1. Enter the command. Examples and descriptions are provided below.
2. Press ENTER.
After the new settings are entered, the new results for that event ID are displayed.
Examples of Event Mask Settings
• To latch event #001, S1 SCR SHORT, use SPT 4 1 +L.
• To disable event #128, CONFIG MODIFIED, from sounding the horn, use SPT 4 100 -A.
• To enable event #012, OUT VOLT SENSE FAIL, to Dial and go into the Event Log, use
SPT 4 12 +D+E.
• To disable all masks for event #120, INPUT CONTACT #1, use SPT 4 120 -D-L-S-E-A.
To breakdown this syntax for the last example:
• SPT — SVT command
• 4 — group parameter, identifying System Setting group under which the E vent Mask settings
reside.
• 120 — item parameter. In this command, that is the event ID.
• -D-L-S-E-A — value parameter. In this case, the minus sign (-)disables all masks for the INPUT
CONTACT #1 event.
NOTE
NO spaces are placed between each mask listed above.
