(high or low) can only occur if the sign of the alarm limit matches the
sign of the reading value.
For example, this may be used in detecting both high charge current and a
high discharge current on a battery shunt. Assume a shunt is wired for a
negative float current reading, and it has a high alarm limit of –6.0 amps to
detect a high float current. It can then also have a high limit of +100.0 amps
to detect a high discharge current. So, in this example there are two high
alarms, with opposite polarity.
(2) Binary Channels: Typical binary inputs include alarm and status indications, and any
input with an on and off state. Each of the binary channels can be programmed to
report an alarm condition, or record this condition for statistical purposes.
(3) Energy Management Channels: See description of Energy Management channels
under "Software Options" found later in this document.
(4) Function Channels: Two or more constants, analog channels, and/or function
channels can be programmed into a single function channel. Examples are using the
data from various analog channels to obtain load sums and averages, or multiplying
two channels together to obtain a power value. Each of the function channels has four
adjustable alarm limits that can be programmed to report an alarm condition, or record
this condition for statistical purposes.
(5) LED Channels: Eight programmable status LED indicators are provided on the front
of the Main CPU card. These LEDs can be programmed to illuminate red, green, or
amber (via the LED channels) at specific events or occurrences.
(6) Relay Channels: Each relay channel can be programmed to activate or deactivate
the associated relay at a specific event or occurrence, or to be associated to an energy
management channel when the energy management and/or sequencing option is
ordered.
Note: Relay channels are not required when the energy management and/or
sequencing option is used to control VPS/NPS PCUs.
1.4.6 Groups: The group feature permits organizing analog, binary, function, LED, relay, and
energy management channels together under one common name as a group. Each group is
programmed with a unique name, and may contain any or all channels. This feature enables
the user to extract information concerning the group, such as alarm reports and statistics, by
using the group name or number instead of each individual channel name.
1.4.7 Alarm Reporting: The system can be programmed to activate an alarm when the monitored
activity connected to any input (or the value of a mathematical expression between various
inputs) increases or decreases past a predetermined level, or when any relay or status LED
indicator associated with the system energizes or illuminates. When an alarm condition occurs
on an input (analog, binary, or function channel), the system can be programmed to notify the
user through local visual indicators, extended alarm relay contacts, remote terminal, pager,
Email, and/or TL1 network (when TL1 option is ordered). Remote terminal, pager, Email,
and/or TL1 network (when TL1 option is ordered) notification of an alarm condition is also
available if an alarm condition occurs on an output (relay or LED channel). All system alarms
are reported via the SNMP interface.
There are two types of alarm reporting mechanisms available for remote terminal, pager, or
Email notification; SYSTEM ALARM REPORTING and INDIVIDUAL USER ALARM
REPORTING. System Alarm Reporting has priority over Individual User Alarm Reporting. The
system has an automatic log-off feature. This feature will automatically log off a user who is
communicating remotely with the system via modem, if the system needs to issue an alarm
report to that or another remote terminal via the modem.
In addition to System Alarm Reporting and Individual User Alarm Reporting, TL1 Report
Messages are issued via the LMS1000 TL1 port when the TL1 software option is installed.
