LCR Troubleshooting Guide
To comply with Weights & Measures requirements, it is necessary to st art and stop each delivery with a fully p acked
hose. Normally, this will be the case. However, there are times where the hose is not fully packed (e. g. after a preset
delivery). As such, the hose must be packed and the register zeroed prior to making the next delivery.
NOTE
: This procedure will not work for an empty or dry hose. If more than 1 gallon or 5 litres of liquid is
required to pack the hose, a delivery ticket must be printed.
To pack the hose at the start of a delivery:
1. Turn the Selector Switch to RUN. DO NOT OPEN THE HOSE NOZZLE. The display will reset and the
solenoid will open the valve, packing the hose.
2. When the display has stopped incrementing, the hose is packed.
3. Then the Selector Switch to STOP. This will de-energize the solenoid and close the valve.
4. Turn the Selector Switch back to RUN. The display will reset to zero, and the solenoid will energize again
and open the valve.
5. Open the hose nozzle and begin the delivery.
6. The Selector Switch can only be turned to STOP one time per delivery, at the start of the delivery, to pack
the hose.
7. To end a delivery with a packed hose, complete the delivery by closing the hose nozzle prior to turning the
Selector Switch to STOP. If making a preset delivery where the solenoid closes the valve prior to the hose
nozzle being closed, the above noted procedure to pack the hose must be conducted on the next delivery.
