2.4.1 Powering on IDEC SmartRelay
IDEC SmartRelay does not have a power switch. The reaction of IDEC SmartRelay during
startup depends on the following:
• Whether a circuit program is stored in IDEC SmartRelay
• Whether a micro SD card is inserted
• Whether this is an IDEC SmartRelay version without display unit (FL1F-B12RCE/
B12RCA/B12RCC)
• Whether IDEC SmartRelay is in RUN mode or STOP mode at the time of power failure
To ensure that the expansion module on IDEC SmartRelay changes to RUN mode, check the
following:
• Has the sliding contact between IDEC SmartRelay and the expansion module snapped
into place properly?
• Is the power supply connected to the expansion module?
• In addition, always ensure that you switch on the power supply to the expansion module
first before activating the power supply to the Base Module (or activate both power
supplies at the same time); if you do not do this, the system does not detect the expansion
module when you start up the Base Module.
