Relay Jumper Configurations
Relay coil power should be supplied by the control. Three independent isolated sources are diode
selected (High Signal Selected) to power each FTM’s relay coil. Jumper banks (four jumpers in one
package) are provided on each FTM to allow field selection of internal or external relay coil power. See
Figures 4-14 and 4-16. If external relay coil power is supplied, the relay coil power jumper bank must be
moved from its defaulted INT. position to the EXT. position.
An FTM includes terminals and internal jumpers to allow its relay coils to be powered by an external
power source. This relay coil power configuration was designed for systems which may not have the
power sourcing capability to power all system modules and relays (custom designed systems). The
5009FT however, has sufficient power to supply all unit modules and relays.
To retain circuit integrity if an external power supply is used for relay
coil power, it must be an isolated 24 Vdc source, with ±5% regulation.
When using an external power source for relay coil power, it is
recommended that a start-up routine be utilized to remove the source
during system power-up and power down. This routine will guarantee
that no relay is inadvertently energized due to system power-up
surges. (By using the FTM’s internal relay coil power this start-up
routine is automatically performed.)
With this system’s power configuration, recommend the control’s internal power be used to supply the
FTM’s relay coils at all times.
Field configurable jumpers are used on FTMs to allow a relay’s latent fault detection logic to be
compatible with different levels of circuit power and to choose which set of relay contacts to test (normally
open or normally closed). Each relay output has two banks of jumpers (multiple jumpers in one package).
One jumper-bank (a set of nine jumpers) is used to match the latent fault detection (LFD) circuit with the
circuit voltage being interfaced with. The second jumper bank (a set of four jumpers) is used to select
which set of relay contacts (N.O. of N.C.) is tested by the LFD logic. During operation, only one set of
relay contacts (normally open or normally closed) can be tested. The set of relay contacts tested should
be same set of relay contacts used by the circuit interfaced to. Refer to Figure 4-16. LFD can be jumper
configured to be compatible with the following circuit voltages:

18–32 Vdc circuit power (meets CE & CSA ratings)

88–132 Vac circuit power (not listed)

100–150 Vdc circuit power (not listed)
