Page 6: Typical Setup
To do this, slide the shutoff valve on the air line away from the reservoir. If using an EFD tank, open the pressure relief valve as well. Before opening the reservoir, check the pressure gauge to verify that pressure is zero (0). -
Page 7: Setup
Setup ➀ Mounting Use the universal mounting bracket (included) to mount the controller either over or under the cabinet. The bracket allows the controller to pivot ➀ 30º from a horizontal position. For panel mounting, a panel mount bracket kit is available (#7000PMK). ➁... -

Page 9: Adjusting The Spray
Adjusting the Spray 1. Turn the nozzle air pressure on the ➀ controller to zero. Using the nee- ➀ dle stroke control knob on the 781S valve, set the fluid flow rate to one or two drops per second. Check flow rate by actuating the controller in the time override mode. -
Page 10: Programming Nozzle Air Delay
Programming Nozzle Air Delay Nozzle air delay is the time the nozzle air continues to spray after the fluid is turned off. When spot marking with low viscosity fluids, the delay can be reduced to prevent blowing out the center of the mark. The delay can be increased with high viscosity fluids and greases to provide a spreading out effect. -

Troubleshooting Guide Trouble Possible cause and correction Be sure that there is power at the wall receptacle. Check the input power fuse. No power If the fuse has blown, check the voltage value in the fuse cartridge window. Be sure that it matches the input voltage. Ensure that the external voltage to the circuit is between 5 and 24 VDC and that End-of-cycle feedback circuit... -
