E4860
CYTECH
Product Description
E4860 is suitable for power supply of small program-controlled switchboard, access network, transmission equipment, mobile communication, satellite communication ground station, microwave communication, and other communication equipment.
When the system power supply is normal, various parameters of the rectifier module and the power distribution unit are controlled by the monitoring module and work according to the preset parameters or user commands. If there is a mains failure, the system will be powered by the battery. With the discharge of the battery, the voltage of the battery begins to drop. When the battery voltage is lower than the alarm valve 46V(settable) on the position machine, the monitoring module will report an alarm signal. If it is lower than 43V, the load output will be directly turned off, and the whole machine will not work. When the external mains supply is restored, the system resumes normal operation (the above monitoring data is the default value of the system, and the user can set it again through the background).
If the operating ambient temperature of the power supply system is ≥ 55 ℃, Power systems need to reduce power output.

Maintenance
(1) Cause analysis and maintenance of communication interruption
Setting reason: the monitoring unit is inconsistent with the position machine;
Maintenance: reset the address of the monitoring unit through the background.
Monitoring module CPU circuit failure or secondary rectifier module circuit failure.
Maintenance: notify the manufacturer for maintenance.
(2) If the reported data is incorrect (including analog value and switching value) and remains unchanged, or the control status is inconsistent with the issued command, or the parameter setting is inconsistent with the actual execution, it may be due to the following reasons:
The input signal is incorrect;
The input circuit is damaged;
Rectifier module failure.
Maintenance: notify the manufacturer for maintenance.
Indication
(1) When the power module operates normally, the green light is on; Otherwise, it will be off. (The green light is off in case of mains failure and no output of the module.
(2) When the power module operates normally, the yellow light is off. Otherwise, there will be temperature pre-alarm, automatic derating, current limiting and fan pre-alarm, and the yellow light will be on.
(3) When the power module operates normally, the red light is off. The red light is on when there are cases of power module failure, such as output overvoltage shutdown, fan failure, over temperature shutdown, remote shutdown or other internal reasons.
LED signal indication | ||||
LED status | Module alarm status | |||
Color of the indicator light | Normal state | Abnormal state | Cause of abnormality | |
Operation indicator | Green | On | Off | When the red light is on, it goes out. See the table below when the yellow light is on. |
Protection indicator | Yellow | Off | On | When the power supply module has recoverable protection, the module ALARM is always on, otherwise, the yellow light flashes when the communication is interrupted; OTP (from ambient temperature above 65 ℃ to module over-temperature shutdown), input over-voltage and under-voltage are valid and over-current, the ALARM is valid. Hibernation shutdown (during hibernation shutdown, the module only lights up the protection indicator, and the module won’t report an alarm.) |
Fault indicator | Red | Off | On | If there is an unrecoverable fault inside the module, the module FAULT is always on, when PS-enable is normal, Vo-OV, fan fault (single or double fan fault), output short circuit and no output occur, FAULT is valid. |
(4) Precautions for use and maintenance of rectifier module
If the red lamp (FAULT) on the front panel of the rectifier module is always on during the normal period, it indicates that the rectifier module has a working fault. At this time, the module should be removed from the system and prepared for maintenance. If the rectifier module is damaged, please contact the manufacturer. It is forbidden to disassemble the rectifier module by non-professional personnel from the factory without permission.
Allow electric hot plug and play
a. When the whole module needs to be removed from operation, unscrew the fastening screw, hold the handle, and pull it out without turning off the AC power supply. In this way, in the power supply system composed of multiple modules, we can make sure the whole power supply system does not need to be powered off when a rectifier module needs to be removed for maintenance, and ensure the normal operation of the power supply system.
b. When the electrical interface of the rectifier module is connected to the power supply system, it must be ensured that the indicator light on the front panel of the rectifier module is off before the rectifier module can be inserted.
