Error 676: Load Cell Balance
A Load Cell Calibration found one or both of the following in error:
Balance Step (typ zero)
Balanced Zero (typ zero)
Posible reasons:
Load Cell cable not connected or defective.
Connections exposed to moisture.
+/-15V supply off range.
Load Cell has been overloaded e.g. due to lack of grease in the loading
plate
swivel or due to dropping of weight without buffers.
Compact15 circuits defective or exposed to condensing moisture.
- Check cables and connections.
- Check +/-15V supplies (Information - Voltages).
- Check Cell resistances thru Load Cell Cable DIN plug first:
Ohms approx DIN plug Load Cell Socket
240 - 243 2 - 4 2 - 4
240 - 243 1 - 5 1 - 5
180 - 183 2 - 1 2 - 1
180 - 183 4 - 5 4 - 5
180 - 183 2 - 5 2 - 5
180 - 183 1 - 4 1 - 4
The middle one of the 3 male pins in the cell socket is no.5 (CW
decrease).
Error 677: Load Cell Calibration
A Load Cell Calibration found one or both of the following Voltages in
error:
Calibration Level
Shuntvalue type 3.5V for FWD, 3.25V for HWD
Posible reasons:
Load Cell cable not connected or defective.
Connections exposed to moisture.
+/-15V supply off range.
Load Cell has been overloaded e.g. due to lack of grease in the loading
plate
swivel or due to dropping of weight without buffers.
Compact15 circuits defective or exposed to condensing moisture.
