9.1 Relay Overview

Fig. 23 shows the recommended Tyco relay
P/N 0-1432793-1. This relay is the only type
of relay to use with the ARP Control up to
v4.x. The v5.x relay just needs to be a
12VDC activation coil type. Terminal 86 is the
+12VDC relay activation and terminal 85 is
the activation ground. These terminals must
have a clamping diode; this is why this type
of relay is required for v4.x and earlier.
WARNING The ARP internal relay is
not warranted against failure due to over
voltage conditions by improper relay
installation.
