Continue Cooling System Installation
Connect the control and status wires between the cooling control panel and the
transmitter with the supplied multi-conductor cable. These low level signals
connect from terminals X2-1 through X2-12 in the cooling control panel to J12-1
through J12-12 on the External I/O board in the transmitter (pin for pin connection).
Figure 2-1 External I/O Board Cooling Connections: J12 & J18
Connect the test load flow switch to J18-9 and J18-10 on the External I/O board in
the transmitter. This will mute the transmitter RF output if there is no coolant flow
through the test load (provided the Patch Panel is in position 2, transmitter to test load).
Specified wire is 7-2-4C, 4 conductor cable. A closed contact is required to operate the
transmitter. Some switches may also use +15V and ground. The connections are as
follows:
•
J18-9 to flow switch terminal 1 (common)
•
J18-10 to flow switch terminal 3 (N.O.)
Depending on the switch the following may also be required:
•
J11-1 (+15Vdc) to flow switch terminal 2 (+DC)
•
J11-6 (ground) to flow switch terminal 4 (-DC)
