BOR-4 Installation and Operation Manual
DESCRIPTION
Component Options:
We provide pads for a NO momentary switch (SW2). This optional switch is con-
nected to input one of K1.
Pads are provided to install an optional sonolert (S1). The sonolert is connected to
K1 via the enable jumper JP13. 5 volts DC is provided for this option.
MODE TERMINOLOGY
Mode 0: Toggle – A low going pulse on input 1 latches the relay, while a
second low going pulse on input 1 releases the relay.
Note: Input 2 must be kept high in order for this operation to work.
Mode 0: Sustained – A sustained low on input 2 will keep the relay closed,
releasing the input, releases the relay.
Note: Input 1 must be kept high in order for this operation to work.
Mode 1: Alternate Action 1 – A sustained low on input 1 causes NO relay
operation. By releasing input 1, the relay will pulse for the
duration configured in the timing description.
Note: Input 2 must be kept high in order for this operation to work.
Alternate Action 2 – A sustained low on input 2 will, pulse the relay
as on the falling edge configured in the timing description. By
releasing input 2, the relay will once again be pulsed for the same
timing duration.
Note: Input 1 must be kept high in order for this operation to work.
Mode 2: Pulse 1 – A falling edge pulse on input 1 generates a relay pulse as
configured in the timing description.
Note: Input 2 must be kept high in order for this operation to work.
Pulse 2 – A rising edge pulse on input 2 generates a pulse as
configured in the timing description.
Note: Input 1 must be kept high in order for this operation to work.
