Majortel System Controller

Integrated Monitor & Alarm Control Module: MTS-Com

Each Majortel DC power system is equipped with a controller module labeled MTS-Com. LCD display, LED indicators and push button keys, on the front panel of the MTS-Com monitor, are standard design elements of this module. The user signal terminal connector is located on the rear of the system and integrates into this module through the internal backplane. Examples of telemetry signaling include temperature, digital input and alarm output; dry contact relay connections. Internally, CAN communication ports facilitate the MTS-Com supervisory signals to and from system elements.

Remote monitoring is capable through the Ethernet port supporting SNMP and Web-TCP/IP protocol. Utilize the front panel buttons to set a system IP Address, Net Mask and Gateway for the specific user network. Start any browser and ping the assigned IP address for access to the main monitor webpage. The most common status/functions can be monitored, configured and changed remotely.

Full Content Explanations

Date and Time

The current date and time can be programmed and stored in the system. The date and time will be used for alarm file time stamping. This status parameter is shown on the main screen of the MTS-Com controller.

Voltage Output

Float: The float voltage setting is the normal charge voltage for the application. A user can program this voltage using the front panel or web page application. Equalize: The equalized voltage can be used for applications requiring elevated charge voltage. Users should consult the battery manufacturer for specific details related to equalize charge routines.

High Voltage Rectifier Shutdown

High voltage shutdown setting will trigger self-protection mode in a system. This programmable setting is used by a controller when monitoring the overall bus voltage. If high voltage is detected, the voltage from each rectifier will cease output operation to protect the load and system.

System DC Voltage Triggers

DC High Beat the scene high voltage trader as used to actually be alarmed four I told each. The alarm automatically clears when the voltage returns to normal. DC Low Low voltage alarms will be triggered if the system voltage loose below dissent point. The alarm automatically clears when the voltage returns to normal.

Current Output

Summary System Monitor Summary current indications are displayed of the system monitor. This current measurement is a combination of the output current, as reported by each rectifier to the central controller. Battery Current Draw Monitor Battery current is measured using a shunt that is in series with the batteries circuit. Battery current draw indications are used to predict run-time, current limit or recharge duration.

Alarm Summary Indicator

Major Type – corresponds to red LED on the front panel. Minor Type– corresponds to yellow LED on the front panel.

Alarm Relay Mapping

Operators may use this option to establish mapping of specific alarms on to one of two dry-contact relays. In addition to mapping an alarm to a relay, the alarm can be classified as either major, minor or ignore.

Alarm Relay Position – Normal Status

All Majortel Systems ship with relay positioning set to Normal-Close relay operation. Relay status position can be programmed using the front panel buttons on the MTS-Com. Dry contacts are designed to make or break the alarm circuit supplied by the operator installation.

Alarm Tone On/Off

Operator programmable option for the audible alarm tone. Default setting is OFF. Active alarm audible tones will time out after 75 seconds. The active alarm will remain on the active status page.

Alarm Active Status

Operators can view the active alarms for the system being monitored.

Alarm History File Clearing

The alarm history file will store 200 events. Each event receives a time stamp. Round file operation will overwrite the oldest table entry.

Charge Rate and Current Limit

See page reference for detailed description of charging parameters.

Force Equalize Charge

Define interval in days Waiting period, in days, between pre-programmed charge routines. Define time limit The time in minutes before an equalize charge will cease and the system returns to float voltage operation.

Battery Size

Operator programmed battery size based on the installation. Numerical value in AmpHours. This value is important to the calculation of the current limit function during recharge.

Low Voltage Battery Disconnect trigger

The voltage set in this parameter is used by the controller to open the internal contactor in the battery circuit. The contact will close the circuit after the system recharged to normal. Typical disconnect voltage is calculated by using 1.75 volts per cell for the battery installation. By example, in a telecom network configuration, 24 cells X 1.75 equals a 42v trigger setting.

Ambient Temperature Monitoring

A temperature probe is shipped with each Majortel power system. Once the probe is connected, the system will register the ambient temperature measured in the location and display this information on the screen. The probe is equipped with a 3 meter cable which allows positioning near the battery. The registered temperature is also used by the controller for the temperature compensation calculations and voltage adjustment.

Temperature Compensation Operation

Define center temperature Default center temperature setting is 25° C. Define compensation coefficient User defined parameter used in the calculation to modify charge voltage in relationship to the change of temperature as measured. This setting will effect system overall voltage.

User and Supervisor Passwords

Two password levels Majortel controller. The user level password is used or basic monitoring. The supervisor level password includes system settings and password control options.

Firmware Revision Monitor

This is a read only field for viewing firmware installed in the controller being monitored.
