Auxiliary Load and Unload

A 10 HP auxiliary load starter is standard on MEYER®-S models. No Auxiliary starters are standard on the SQ; they are optional. The overload relay will need to be modified for lower horsepower connections. It can also be used as a control relay to start loading conveyors or gates on demand-fill systems.

An auxiliary unload conveyor should be interlocked into the Dryer to confirm that the unload path is operating. An unload interlock relay is provided for that purpose and accepts a 120vac signal from the conveyor.

To prevent a hazardous condition, all SAFETY devices, including wiring of electrical devices are arranged to operate in a “FAIL-SAFE” manner. That is, if a power failure or failure of the device occurs, a HAZARDOUS CONDITION will not result. To prevent a hazardous condition, the machine and all associated equipment MUST be PREVENTED FROM RESTARTING on its own after a power failure when power returns or a jam is cleared. A MANUAL re-start is required.

Do not install or use any method to start or restart the Dryer which bypasses factory- installed SAFETY features.

Connecting the Monitor to the Control Panel Cabinet

Once the Dryer has been properly wired and GROUNDED and with a 10' [304.8 cm] Ground Rod, located and connected as close to the Dryer frame as possible, connection of the Master Control Unit is as follows:

1. Location of the Monitor

The QUANTUM® Monitor is normally located in an office or control room. Although the Monitor can be located up to 1000 ft [3 048 m] away from the Control Panel, keep in mind that starting, calibrating and servicing the Dryer will require routinely walking between the Monitor and Control Panel / Dryer. If wall mounting is desired, the Customer must supply adequate supports. Controller locations should be planned in detail with your installation provider before installing the Dryer.

2. AC Power Supply

The AC power supply to the Monitor should be from the same power source as that of the Dryer Panel. This means that the Monitor should not be powered from an AC supply that is from a different phase or a different power transformer from the pubic utility service. Failure to follow this instruction may cause equipment damage.

3. Running the Communications Cable

IMPORTANT!    Do NOT run the Com Cable in the same conduit with the AC power wiring, which runs from the Control Panel to the Monitor.

Do not run the Com Cable with any other wiring. The Com Cable should be run in conduit. Also, do not coil up excessive Com Cable in the Control Panel or at the Monitor end. It is better to keep the lengths of exposed wire as short as possible to minimize the effects of radiated emissions.

The drain wire of the communications cable (RS485 Data Cable) should be connected to the ground lug inside the Dryer Panel Box and no connection should be made at the Monitor end.

Terminate the wiring from the Monitor to Dryer Panel box as follows: Black wire from Monitor----------------Slave CPU board TB2 #16 (+)

White wire from Monitor----------------Slave CPU board TB2 #15 (-)

Locate the Monitor in an indoor area where it is protected from physical damage and exposure to elements of other dangers that could void the Warranty.
