How to Test Heater in Summer?

The temperature is very high in summer, after installing engine heater but you don’t know how to test? Engine lack of coolant liquid, heater overheat always happen? Customers complaint and hidden danger happen occasionally?

What should we do?

SmartGen new generation heater HT10M / HT22M / HT40M emerged to solve these problems!

New features are as following: With Test button: If heater doesn’t work or overheat indicator doesn’t light up, users can press Test button to see if the heater can work normally; With overheat protection: When heater enters into overheat protection status, heater will stop heating. If heater temperature falls below the reset temperature limit of overheat protection thermostat(95ºC), users need to press reset button and heater enters into auto mode again.Avoid heater overheat! kinds of heating temperature are optional ( 40ºC, 50ºC and 60ºC); There is a water drain valve with seal ring on the bottom of the heater; With power, heating and overheat protection light indicators; HT10M/HT22M has same installation dimensions and installation methods as the previous generation HT10/HT22.

New heaters will continue to be updated…

HGM4020T Helps CHINA TOWER

CHINA TOWER is the largest telecommunications tower infrastructure service provider in the world. As of December 31, 2017, CHINA TOWER has operated, managed 1872154 sites and served 2687475 lessees. According to the Sullivan report, as of December 31, 2017 and in the whole year of 2017, CHINA TOWER ranked first among the global telecommunication tower infrastructure service providers according to the number of site, the number of lessees and the income computation. To meet the control need of telecommunications base station generator sets, SmartGen has developed a new generation of communication base station dedicated generator sets control module-HGM4020T.

Main Functions: 1.Generator room temperature detection,auto start under high temperature, control air conditioning to start; 2.Battery voltage monitoring,auto start generator sets charging under low battery voltage; 3.Mains/load,mains /air conditioning ATS transfer automatically; 4.The mains rules can be configured, 6 start conditions can be combined; 5.With mains,generator sampling and display protection functions; 6.With current sampling display and protection functions; 7.With USB,RS485 communication interface; 8.6 relay outputs, 5 digital inputs(7 channels can be defined at most),2 analog inputs(4 channels can be defined at most); 9.Event log, real-time clock, scheduled start & stop generator; 10.Entrance guard detection function. Advantage: 1.Small, adapt to the demand of telecommunications base station generator sets; 2.Feature-rich, many rules can be defined in this module; 3.With RS485,USB interface; 4.According to the size of generator sets power, ATS switching can be defined; 5.Generator sets auto control integrates with ATS control.

Things Go Contrary Against One’s Wishes Because of Details

A hospital in Shandong selects two 500kW gensets to be paralleled and adopts control module HGM9510. One genset is main and another genset is reserve, when mains is abnormal, the two gensets start (control module is auto mode)and close at same time.

Specific methods of trouble shooting for this problem:

1. Check MSC communication, after checking the communication is normal.

2. Check whether the programmable input is selected as “first priority”. After checking, it is selected as “first priority” and the main / reserve switch is normal.

3. Check whether the mains signal detection are in same phase. After checking, they are in same phase.

4. Check remote start input, we found that the remote start is selected as “remote start on-load”, it should be selected as “remote start on demand”, after change the failure is solved.
