NOTE:
TERMINALS 12 AND 13 ARE FOR MODULE POWER SUPPLY.
TERMINALS 11 AND 14 ARE FOR AUXILIARY OUTPUT POWER SUPPLY.
JUMPERS JP2 AND JP3 MUST BE REMOVED IF AN AUXILIARY POWER SUPPLY IS USED.
NOTES:
1. JUMPER JP1 MUST BE REMOVED IF EXPLOSIVE INITIATOR IS USED.
2. RESISTOR IS USED TO COMPENSATE FOR 10 OHMS CIRCUIT RESISTANCE.
RESISTOR MUST BE RATED 1 WATT MINIMUM (WIRE-WOUND RESISTOR PREFERRED).
WHEN MEASURING THE TOTAL RELEASE CIRCUIT RESISTANCE,
USE AN OHM METER WITH A CURRENT OUTPUT OF 10 MA MAXIMUM.
3. MAXIMUM NUMBER OF EXPLOSIVE INITIATORS PER CIRCUIT IS 12.
EACH CIRCUIT MUST NOT EXCEED 10 OHMS INCLUDING CABLE RESISTANCE.
