VII. UPS REMOTE MONITORING AND CONTROL
Following external connections are available for LION Series UPSs.
Communication by serial port connection.
Dry contact (interface board) connections.
Remote monitoring panel.
Using one of above communication options is satisfactory for remote monitoring and control in most of the
systems. But in some systems may use 2 or 3 of above options at the same time. In this case accessories group
produced by Tescom may help to make appropriate solutions.
7.1 Using Serial Port
Two serial communication port is included on LION Series UPS cabinet (com1 and com2). Both of them may be
used for user communication. But in service status duty of com2 port is changed and set as service port in Options
Menu.
All data of UPS can be accessed by this communication way. All the voltage and current values measured by
UPS, alarms, warning and status messages can be monitored.
Because the communication system is designed in an interactive manner, UPS may get commands from
monitoring and control units. These commands are listed below:
Switch to BYPASS
Switch to INVERTER
SOUND on/off
Adjust UPS time and date
Quick BATTERY TEST
BATTERY TEST until battery low alarm
CANCEL battery test
Turn off UPS output voltage immediately (SHUTDOWN)
Turn off UPS output voltage after delay (WAITING SHUTDOWN)
Turn off UPS output voltage (SHUTDOWN) and turn on UPS output voltage (WAITING RESTART)
CANCEL SHUTDOWN
RENAME UPS
These commands are evaluated only if
REMOTE CNTRL: ON
option is selected in
OPTİONS/COMMUNICATION
OPTIONS
menu and if user password is sent from this (com2) port. Otherwise UPS doesn’t perform these
commands and only information can be obtained from the ports.
Special softwares are required in order to use the serial communication ports. Some of the commands above have
special functions and they can only be activated and used by operating TMON program groups on a PC that is
serially connected to UPS.
TMON program group includes softwares developed by SINERCOM.
Additionally, remote monitoring and control is provided in every kind of operating systems, by using worldwide
known and continuously devoloping software programs. These softwares can be supplied from SINERCOM.
7.2 Serial Communication Port Connection Cable
The maximum length for RS232 communication cable should be 25 meters. For remote panel and UPS connection
the same pin configuration is valid. Connection terminals of RS232 cable is shown below for com1 and com2
