Figure 2-33. Wiring Diagrams for Initiator-Based Releasing Devices
DO NOT INTERMIX DIFFERENT TYPES OF INITIATORS IN THE RELEASE CIRCUIT.
CAUTION:
WHEN MEASURING THE TOTAL RELEASE CIRCUIT RESISTANCE, USE A
OHMMETER WITH A CURRENT OUTPUT OF 10 mA MAXIMUM.
1.
2. Choose limiting resistor so that total initiator circuit resistance is 10 ohms +/- 1 ohm.
: For 93-002009-004 initiators, choose the limiting resistor so that the
total circuit resistance (including field wiring) is at least 10 ohms, not to exceed
13.6 ohms.
Exception
3. Maximum number of Squibs per circuit is:
12 for 31-199932-004
8 for 93-002009-004
6 for 93-191001-001
Route non-power-limited wiring at least 1/4 inch away from all power-limited wiring.
Place non-power-limited wiring inside conduit.
