NOTES:
1. Connect only UL Listed 24VDC devices to indicating
circuits.
2. Connect EOL Diode assembly IN SERIES with solenoid
on release circuit
3. Install EOLR (provided) on all unused circuits.
4 Polarity is shown on indicating circuits in an activated
(off-normal) condition.
5. Polarity reverses when output is activated.
6. Maximum current per output is 3 Amp. Maximum voltage
is 33VDC.
7. Outputs identified as Release are Special Application. All
other outputs are Regulated 24 VDC, Rated 3 Amp each, 3
Amp total for all 4 circuits.
8. All initiating and NAC/Release circuits are supervised and
power limited. See Main Board Wiring Specifications for
wire routing instructions. All frequencies are continuous.
9. Refer to Appendix A for test and maintenance information
