Putting the Terminal Command Together
For example, a unit only has the Remote Source Selection and Dual-Output Breaker options installed.
Checking the bits list under Options_1 on page 92, bits 7 and 0 each must be set to 1 to indicate that these
options are installed.
The bit setting is as follows, starting with bit 15 on the left and going down to bit 0:
0000 0000 1000 0001
With the bits combined in groups of four, the binary settings can be translated into hexadecimal values.
The first two groups in the sample equal zero (0). In the third group, 1000 in binary translates to 8 in hex. In the
fourth group, 0001 in binary translates to 1 in hex.
In hex, this equates to (digits in the value parameter cannot have spaces between them):
0081
So your command to indicate that the Remote Source Selection and the Dual-Output Breaker are installed would
be:
SPT 2 6 0081
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 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/PDU via the Terminal 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 13.
• 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 by a minus sign (-) to disable it.
Only the mask that is passed (enabled) is applied when the event occurs.
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.
NOTE
NO spaces are placed between each mask listed above.
