Frequently asked questions:
Q: ERAmega supply working voltage is 12V or 24V ?
A: Both. Via the build-in switching power supply, ERAmega adapt automatically to any voltage from 9V to 32V DC.
Q: Power supply of ERAmega is it isolated ?
A: No. All lines should be healthy and clear from any leaks, before install.
Q: Does it have ERAmega reverse polarity protection ?
A: Yes. If by accident connected in reverve polarity, no damage occur. However not work either, until polarity corrected.
Q: Does ERAmega have protection fuses ?
A:Yes bipolar, TR5 type 500mA.
Q: Does input channels have protection filters ?
A: Yes, they can tolerate up to +100V DC.
Q: Why a panel need auto brightness control ?
A: When installed on the bridge, the variation of ambient light is huge. A constant level of light, may cause annoying brightness during night, and hard to see indicators during day. Automatic brightness, fix this problem.
Q: What is cable monitoring ?
A: For additional safety is recomended input cables to be monitored.
For this reason a terminal resistor installed at the end of each line (preferably on the sensor). Resistors included in the package. When ERAmega find the resistor at the end of the line, recognize the line as helthy.
If is difficult to place the resistor, cable monitoring can be disabled.
By default cable monitoring disabled.
This setting is individual for every channel.
Q: What do they do the programmable relays ?
A: Once they assigned for one or more channels, they activated when one of those get alarmed.
A common use of those relays is to activate shut down of a generator, when low oil press or high water temperature occur.
Q: What does delay option ?
A: A common use of it, is for the bilge sensors, were the moving fluids cannot give a steady reading, or for alarming of a refrigerator when door left open for to long.
Q: How easy is the setup ?
A: More easy than ever. ERAmega doesn't have DIP switches, and no need computer for setup. Just hold "Setup" button (located at the back of the panel) during power up, and then by the front panel buttons you can alter easy all adjustments.
A setup table is preinstalled in the front window of the panel, to help installer navigate through menu.
If this isn't enough for you, user manual provide detailed directions about setup.
Q: What does the external siren relay ?
A: When ERAmega is installed inside a control room, the isolation walls and the noise of the engine room does not allow the audible alarm to travel out off the control room. An external siren installed inside the engine room were usually the crew located, can solve this problem. Additionally is an extra safety, when the build in buzzer fail.
Q: Can I install 2 ERAmega for the same sensors ?
A: Yes you can. When cable monitoring is disabled, this can be done without any consideration. When cable monitoring is enable you can do it also. The only modification is the replace of each default 4.7kΩ terminal resistor, with a bidirectional 2V zener.
Q: What does the Test button?
A: Initially test each indicator, and inform user about the condition of each channel: Normal, alarm, or cable fault. At the end, all led light up with the buzzer activated, and then normal operation begin.
Q: What does the cancel button ?
A: Cancel button work in a very smart way. Combine mute, and acknowledgement together. In a new incoming alarm led flashing and buzzer sound. By pressing cancel button once, audible alarm stops but indicator still flashing. This allow user to evaluate the situation, without distracted by the audible alarm. Flashing indication show new incoming alarm, steady on show old alarm, and off show normal condition. Pressing twice the cancel button, indicator turn steady on, passing it to the old alarms, and stay there until sensor return to normal position.
Q: The cancel button does work separately for each channel?
A: Yes it does. After a cancel of a channel, the panel is ready for the next new incoming alarm.
