Description
FMR15102 can be used in noisy environment and is least affected by electrical interference. This makes FMR15102 an ideal choice for use in heavy industrial environment.
Modes
1. Momentary Mode
If the dipswitch is off the relay will be in momentary mode.
2. Flip Flop Mode
If the dipswitch is on the relay will be in flipflop mode.
3. Latching
If latching is required (Relay stays on until power is removed) the latching link should be inserted and soldered into the two holes to the left of the 2-way dipswitch and the respective dip switch to be on. Dip Switch 1 will put Channel 1 in latching and Dip switch 2 will put channel 2 in latching mode.
Coding
The 12 way dip switch on the receiver sets the 12 bit unique code for the system. This has to be matched to that on the transmitter.
Apart from the 12 way dip switch there will be an additional dip switch depending upon the receiver type:
- Two channel receiver will have a 2 way dip switch.
This DIP switch on the right side of the 12 way dip switch denotes the channel. See table below.
Generally to use a 2 channel Tx to 2 channel Rx match all the 14 dip switch (12way + 2way just on the right side of the 12 way).
To use a 2 channel Tx to control 2 x single channel receivers, first match the 14 dip switch positions and on the receiver, 15th dip switch OFF is Ch1 and 15th dip switch ON is Ch2.
To use a 2 channel receiver with 2 x single channel transmitters, first match 14 dip switch and then the Tx with Sw15 OFF will activate the Ch1 on the receiver and the Tx with Sw15 ON will activate the Ch2 on the receiver.
