Figure 5.6.5 shows using two relay outputs to control and supervise 1 or 2 Mini-Gen or
ISO8201 Strobe Driver modules.
2 x 27k EOL resistors are required. If only one Mini-Gen/Strobe Driver is fitted, put one EOL
at the end of the field wiring and the other across the DC IN +ve, -ve terminals. If two
branches or 2 Mini-Gen/Strobe Drivers are used (1 branch each) put the EOL at the end of
each branch.
Program the first relay as supervised and the 2
nd
relay as not, with both relays activated by
the same logic. Also the first relay must be programmed so that supervision is disabled
when the relay is activated.
