Alternatively:
If the device's main switch is a rocker-switch it must be pressed down on the
"ON"-side (upper portion) for approx. 1 sec to achieve activation, indicated by the
"POWER"-LED flashing (e.g. CRONOS-PL devices).
To switch the device off, press the rocker switch down on the OFF-side (lower portion)
for approx. 1 sec.
2.8 Remote control
As an alternative to the manual main switch, the device can be switched on and off remotely, by control
signals that are accessible at the "REMOTE" connector of the device. These can be operated by externally
installed manual switches, relais contacts or electronic switching elements.
There are
several distinct switching functions and operating modes are available as described in the
tables below. The main operating mode, available for all types, is the basic ON/OFF push button action
performed with one single temporarily closing contact: Connecting the signals "ON/OFF" (Pin13) and
"SWITCH" (Pin2) for at least a short time, activates the device as with the green
. Once
powered up, the device can be switched off by connecting the two signals once again, that means at least
releasing the connection and connecting again.
