Input Connector TB2
Refer to Table 3-5 and Figure 3-4.
The inputs from the TB2 input connecter (3) are
designed for contact closure or an open collector
output. With the exception of the 4-20 ma remote
analog input, the input terminal voltage is 24 Vdc
and will source about 8 ma.

12 4-20 ma input
or
0-10 Vdc
X NA Remotely varies the lamphead output power
when the unit is in the Remote mode. The
lamphead power has three setpoints:
Lo (35%) = 0-3 Vdc or 4-7.5 ma
Med (65%) = 4-5.5 Vdc or 11-14 ma
Hi (100%) = 6.5-10Vdc or 17-20 ma
13 4-20 ma input
or
0-10 Vdc
(ground)
NOTE: If this input is used to vary the
lamphead power and the current drops below
about 3 ma, the lamphead power becomes the
SETPOINT power. If remote variable power is
not required, leave these terminals
disconnected. Reversing the ground and
signal wires can cause erratic system
operation.
