4. INSTALLATION
4.115 Volts A/C
a.The
b.The input 115 volts AC should be wired to the lower terminal strip as indicated by the decal in the Moisture/Matic box (L1, N and Gnd).
5.Additional Signal Outputs
a.Signal 1 out and signal 2 out are located on the lower terminal strip. Each “signal out” consists of ‘C’ (common), ‘NO’ (normally open), and ‘NC’ (normally closed) contacts. These signals will operate when in the ‘Automatic’ mode and when the moisture of the grain exceeds 1.3 percent over the moisture set point setting. These contacts can be used on any accessory equipment or warning device that requires less than five (5)
Amps at 115 V AC.
6.The MCR relay output sends 110 VAC signal when the control power switch is set to “control”. This allows for switching between the CUD and the “Dryer Control”. When the control switch is in “Monitor” the MCR signal will not be present. This will allow monitoring when using temperature based control or batch control.
7.The unload monitor will allow the printer to print only when the dryer is unloading. Terminal 6 on the unload monitor needs too have 110 VAC to enable the printer to print. If a dry contact, such as in AUX is used, power may be used from terminal 5. If this feature is not required, jumper may be placed between unload monitor terminals 5 and 6.
8.Check to make sure that all dryer safety switches are functioning correctly after the wiring is complete.
CAUTION 
NEVER APPLY AC VOLTAGE TO THE UPPER SENSOR TERMINAL STRIPS.
ALL WIRING MUST BE DONE IN ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE.
ALL WIRING SHOULD BE DONE BY A QUALIFIED ELECTRICIAN AND SHOULD BE TO ALL CODE STANDARDS TO AVOID POSSIBLE BODILY INJURY OR DEATH.
GRAIN BINS AND/OR DRYERS WITH ELECTRICAL EQUIPMENT IN OPERATION MUST BE GROUNDED.
DO NOT MODIFY OR BYPASS ANY SAFETY SHUTOFFS!
