I have a 3 phase installation and want to monitor voltage and current. How do I do this?
Digital or analogue meters are available (discuss with your client their needs). You will also need selector switches for voltage and amperes. You will need CTs for the ammeter appropriate to the maximum demand of the installation.
Do I have to configure kWh meters?
Yes. The meter does not know the CT ratio you have connected. Failure to configure will result in incorrect readings. Please download the relevant kWh meter user instruction sheet for this procedure.
Are Hager CTs sensitive to the direction of current flow?
No. When the CTs are used in conjunction with Ammeters and Selector Switches, the polarity of their installation is not critical. When the CTs are used for Energy (kWh) Measurement, the relative polarity to CTs with regard to the Voltage connection.
How do I know how accurate the kWh reading will be?
Apart from the meters accuracy, the accuracy of the final installation depends upon the CTs used as well as the length and size of connecting cables.
Can I use Hager kWh meters to monitor usage on 2 tariffs at the same time?
No.
I want a device to turn lights off 5 minutes after I turn the light switch off. How do I do this?
This function is called delay OFF, it is important to recognise the actual functional control you want. Select the device, EZ002 and adjust the timing dials to match your need.
Can I use a DC voltage to control a Time Delay Switch?
Yes. A DC control voltage (12 – 48V DC) can be used with all Delay Timers. The switched contacts are rated at 230V AC. See the user instructions for the connection of the various voltages (AC and DC).
Can I switch a 16A load on timer contacts rated at 16A?
In theory yes, in practice NO. We do not advise this. We do not know what loads are being connected, therefore, it is safer to use a Contactor to switch the load and not the relatively expensive timing device.
I want to operate a school bell during school hours only, not on weekends or holidays.
A Hager EG293B or EG493E time clocks are the only devices that will comply with this application. We recommend programming these devices with the supporting EG003G USB interface and the EG003 software, a computer based program that enables easy programming of EGxxx series time clocks. The programme is entered into the computer and then downloaded onto the key supplied with the clock. This enables easy storage and modification of programmes.
You can also use the EGN timers (EGN100AU 1 channel, EGN200AU 2 channels, EGN400AU4 channels) which are easily programmable with the Hager mood application. The Hager mood app can be downloaded on the app store or google play. When your time schedule program is completed you can transfer it to the timer via Bluetooth technology.
I have installed an EG103E and now the time is one hour out due to daylight savings. Do I have to re-programme the Time Switch?
The EG103E has a daylight savings automatic function which requires activation and the setting of dates for changes. Once set, the dates will be adjusted for each of the following years automatically. Refer to the user instructions for more information.
Note 1 - Select the 'USER' option, do not select 'AUS as the preset dates are incorrect.
Note 2 - The change to Daylight Savings time is the first date entered, then the change date for Eastern Standard time.
The EGN timers are automatically updated to summer/winter time change.
How can I secure a Time Switch Programme from tampering?
The EG103E and EG203E can be locked with the use of the EG004 Locking Key. The EG403E, EG293B and EG493E can be secured by programming in a PIN code. It would also be advisable to back up the original programme on a programming key.
Why isn't my EG071 Time Switch switching according to my programme?
The Time Switch may be in the override position. Press and hold the ON/OFF button for 3 seconds to revert to the auto mode.
