Mute
The
Mute key will silence the audible alarm while an alarm state exists.
The operation of the alarm mute has two pre-settable modes. (See User
Programmable Set Point Instructions).
In mode 1, the
Mute key will continue to silence the audible alarm until a new alarm
condition occurs, or the
Reset key on the front panel is activated.
In mode 2, the
Mute key will continue to silence the audible alarm until it is reset by
the
Reset key on the front panel. Therefore, any new alarm that occurs after the Mute
key has been activated will not operate the audible alarm.
5.5.1.3
Constant Current Charging
The MCR Series Rectifier has a built-in constant current charging function to enable
the user to perform commissioning charges when new batteries are installed, or
when cycling the existing battery bank.
To perform constant current charging, it is necessary to ensure no load is connected
to the charger (due to the high output voltage). The system has built in protection that
will terminate the constant current mode if any load current is detected.
Select the Constant Current Setting menu. (See User Adjustable Set Point
Instructions.) A warning screen will appear informing the user to ensure the load is
disconnected. Press the
Mode key on the rectifier front panel to clear the warning.
Set the Constant Current Mode to ON by using the
Arrow keys.
Pressing the
Mode key will display the period which the charger will operate in
Constant Current Mode. Adjust by using the
Arrow keys (if necessary.)
