WIRING INSTRUCTIONS

TEMPERATURE WIRING INSTRUCTIONS
(Continued)
Note:
When using a shielded cable, be sure to connect
only (1) end of the shield to ground at the controller.
Connecting both ends of the shield to ground may cause
a ground loop. When removing the shield from the
sensor end, make sure to properly trim the shield to
prevent any chance of shorting.
Note:
If the controller requires a (2) wire input for a RTD,
connect the (2) common wires (same color) together. If
the controller requires (3) wires, use (3) individual wires -
see
FIGURE 6
(p. 3).

REVERSE ACTING OUTPUT
(Continued)
To change the transmitter to reverse acting or back to
direct acting, set switch 4 to ON to put the unit in setup
mode. After switch 4 is on, turning switch 2 to ON will put
the unit in direct/reverse acting mode. When switch 2 is
set to ON, the output can be used to show if the unit is in
direct or reverse acting mode. For direct acting, the
output will be 1 V for 0-5 V, 2 V for 0-10 V, and 7.2 mA for
4-20 mA. For reverse acting the output will be 4 V for 0-5
V, 8 V for 0-10 V, and 16.8 mA for 4-20 mA.
With switches 2 and 4 ON, each time switch 5 is set to ON
the output will change to reverse acting or direct acting.
To reset the unit to the default setting, toggle both
switches 5 and 6 ON then OFF while both switches 2 and
4 are ON.
When all calibration is completed, remember to place the
switches back into the positions that correspond to the
output needed as shown in
FIGURE 7
.
HUMIDITY REVERSE ACTING OUTPUT
The output is direct acting and can be changed to
reverse acting mode. The output range stays the same
but the corresponding RH value is opposite.
Example:
Direct Acting (DA)
0-10 V output mode,
0 V = 0% RH and 10 V = 100% RH
Reverse Acting (RA)
0-10 V output mode,
0 V = 100% and 10 V = 0%
OUTPUT SIGNALS
Switches 6, 7, and 8 are used to set the RH output signal.
Refer to
FIGURE 7
for switch settings.
RH CALIBRATION INSTRUCTIONS
Note:
This is only a single point calibration. All transmit-
ters are factory calibrated to meet/exceed published
specifications. Field adjustment should not be necessary.
The dipswitch allows the user to calibrate the sensor
through the software. Setting switch 4 ON will put the
transmitter into setup mode allowing the increment and
decrement to work.
Once in setup mode, the output will change to 50% (2.5
V for 0-5 V, 5 V for 0-10 V, 12 mA for 4-20 mA). Each
increment or decrement step will cause the output to
change by 0.1 V for 0-5 V, 0.2 V for 0-10 V, and 0.32 mA for
4-20 mA in setup mode. This can be used to show the
user how far offset the transmitter is. To see the starting
point again set switch 1 ON. This will show the 50%
output again. When the unit is out of setup mode the
output will go back to RH output. The maximum offset is
10%. There can be a total of 20 increments.
