2.4 PC Board Settings
2.4.1 On-Card Jumpers
NOTE: Dot position means jumper goes from center pin to the pin nearest the dot on the PCB. Also the first
jumper designation is for switch A (J1) and the second is for switch B (J101).
JP1, JP101 - 3-pin jumper that works with JP3, JP103
In the dot position when channel 1 alarms the 1582-14 will switch to channel 2 until channel 2 alarms.
At this point, if channel 1 is still in alarm, the switch will stay on channel 2. When the channel 1 alarm
clears if channel 2 is still in alarm, the switch will switch to channel 1.
In the non-dot position, operates in conjunction with JP3 as noted below.
JP1, JP101 normal position - non-dot and operates in conjunction with JP3, JP103 as noted below.
JP2, JP102 - Input alarm condition 3-pin jumper
In the dot position open is normal operation, ground is alarm
In the non-dot position ground is normal operation, open is an alarm.
JP2, JP102 normal position - dot
JP3, JP103 - LATCH to CH2 mode on / off - 3-pin jumper effective when JP1 is in the non-dot position.
With JP3 in the dot and JP1 in the non-dot, when channel 1 alarms, the 1582-14 switch switches to
channel 2 and stays there until the reset button is pushed on the front panel or by an external closure to
ground on the remote RESET pin on J8, and then it switches to channel 1. (If channel 1 alarms are
cleared ). If in the ICS mode and originally set to CH2 the 1582-14 will not switch if CH2 alarms.
Only the RESET functions (front panel pushbutton or J8 closure to ground) will return the switch to
CH1.With JP3 in the non-dot and JP1 in the non-dot, when channel 1 alarms the 1582-14 switches to
channel 2 until the alarm on channel 1 clears and then the 1582-14 switches back to channel 1
automatically.
JP3, JP103 normal position - dot .
JP4, JP104 - CH2 alarm enable / ignore - 3-pin jumper dot position - Failure in CH1 will cause
the 1582-14 to switch to CH2 even if CH2 is in alarm. LEDs will correctly show CH2 alarm status
Non-dot position - Failure in CH1 will cause the 1582-14 to switch to CH2 only if CH2 is not in alarm.
JP4, JP104 normal position - non-dot
