RECEIVER MODES
The ST620RF Receiver can operate in three different modes – AUTO or MANUAL, and also has a FAILSAFE mode of
operation. These modes are selected by using the slide switches on the front of the Receiver:
MANUAL MODE
Moving the slide switch to the 'Manual' position selects the Manual operation mode of the ST620RF. In Manual mode,
the Receiver ignores the RF signal from the Control Centre and controls the output relay manually, based on the setting
of the Failsafe mode switch. Please be aware that if the Control Centre is operating in Service mode when changing the
Receiver switch position, the relay output may be affected.
