TransPortalTM Interlock Monitor
2.5.4. Power Input
The TIM is powered by 8–30VDC. Although the power input is fully isolated and
protected against reverse battery connection, observe the polarity when connecting
power to avoid damage to the unit.
2.6. Top Panel Keypad/Displays
Due to the persisted IP network connection that the unit maintains, all monitored status,
alarm information, and configuration settings can be managed over the network
(Remote Operation). When on-site with the unit (Local Operation), the best way to
interact with the unit is to plug a browser-equipped computer into the unit and interact
with its embedded server.
2.6.1. Top Panel Keypad
The keypad located on the top panel is not used in this application.
2.6.2. Top Panel Indicators
Four red-green LED indicators are on the TIM top panel. At a glance, these indicators
display the status of four major functional areas of the unit. Typically, if any of these
indicators is red rather than green, there is some condition or situation that needs to be
explored, typically using the Keyboard/Display navigation or a browser-equipped
computer and interacting with the embedded server inside the unit.
2.6.2.1. Operational State
The Operational State LED indicator is not used in this TIM application.
2.6.2.2. Alarm Conditions
The Alarm Conditions LED indicator is not used in this TIM application.
2.6.2.3. Communication Status
The Communication Status LED shows the status of the TIM-to-MLK (not WAN)
connection. Communication status verifies (green) that the TIM has established a valid
serial link to the MLK. Periodically the TIM may be momentarily disconnected when
processing large event logs from the MKL. During these brief periods and during TIM
startup (which can last for 90-120 seconds), the TIM continues attempting reconnection
with the MLK, and the Communication Status LED will be red. The status of the serial
connection between the TIM and the MLK is also communicated to the host system
using specific SNMP traps.
