Issue 0.3
TEST LOAD INTERLOCK
: Provides an interlock for the test load. If the test load
interlock is open, the transmitter routed to the test load is interlocked off. Install a
suitable length of shielded cable between terminals TB2-7 (core) and TB2-8 (shield)
of the control/monitor assembly and the test load's interlock connection (see para.
2.3.7 for details on the test load).
XMTR A INTERLOCK
: Provides an interlock for the NX200 Transmitter (transmitter A).
If a system interlock or the test load interlock is open, or if the RF contactor has not
completed a transfer, transmitter A is interlocked off. Install a suitable length of 2-
conductor shielded cable (WE32) between terminals TB1-1 and TB1-2 of the
control/monitor assembly and transmitter A's interlock circuit (A11A1J6, see the
NX200 Transmitter manual for details).
XMTR B INTERLOCK
: Provides an interlock for the existing on-site transmitter
(transmitter B). If a system interlock or the test load interlock is open, or if the RF
contactor has not completed a transfer, transmitter B is interlocked off. Install a
suitable length of 2-conductor shielded cable (WE32) between terminals TB3-1 and
TB3-2 of the control/monitor assembly and transmitter B's interlock circuit (see the
transmitter's instruction manual for details).
XMTR A ALARM
: Provides a means to audibly monitor faults in transmitter A. Install a
suitable length of shielded cable between terminals TB1-3 (core) and TB1-4 (shield)
of the control/monitor assembly and pins 2 (core) and 1 (shield) of J5 of transmitter
A's remote interface PWB (A11A4).
If the
MUTE
toggle switch on the control/monitor
assembly's front panel (see Figure 3) is not set o
MUTE
, you will hear an audible
alarm when a fault occurs on transmitter A. If the toggle switch is not set to
MUTE
,
the audible alarm will be disabled.
