Response
Receiver pulses. Decoder remains non-responsive unless three or more pulses are
received in a 5-second interval. Only one relay stays powered, determined by the
number of pulses sent to the receiver:
received in a 5-second interval. Only one relay stays powered, determined by the
number of pulses sent to the receiver:
Ø 3 pulses closes the 3-pulse relay.
Ø 5 pulses closes the 5-pulse relay and opens the 3-pulse relay.
Ø 7 pulses closes the 7-pulse relay and opens the 5-pulse relay.
Decoder does not respond to signal elements of less than 50 milliseconds and does
not require signal elements of more than 100 milliseconds.
Ø 5 pulses closes the 5-pulse relay and opens the 3-pulse relay.
Ø 7 pulses closes the 7-pulse relay and opens the 5-pulse relay.
Decoder does not respond to signal elements of less than 50 milliseconds and does
not require signal elements of more than 100 milliseconds.
Relay Response
Field-changeable to operate the relays in the following sequence, by removing
diodes D3, D4, and D12.
diodes D3, D4, and D12.
Ø 3 pulses closes the 3-pulse relay.
Ø 5 pulses closes the 3- and 5-pulse relays.
Ø 7 pulses closes the 3-, 5-, and 7-pulse relays.
Ø 5 pulses closes the 3- and 5-pulse relays.
Ø 7 pulses closes the 3-, 5-, and 7-pulse relays.
Timer
Holds the relay(s) closed for 15 minutes. In fast test mode, timer releases relays
after 20 seconds.
