10.2 INFORMATION ON DISpLAY
[
LO VI
]
When power supply voltage drops below the permissible minimum,
minimum allowed being
92Vac (for 115Vac version)
or 184Vac (for 230Vac version), pump will stop and display will show [LO VI], meaning LOW VOLTAGE INPUT.
[
hI VI
]
When power supply voltage increases above permissible maximum,
maximum allowed being
134Vac (for 115Vac
version) or 268Vac (for 230Vac version), pump will stop and display will show [HI VI], meaning HIGH VOLTAGE INPUT.
[
SYNC
]
Every time pump is powered by the main electrical supply, display shows [
SYNC
] for 1 second. The message indicates that
the microprocessor is analysing power supply frequency. This auto-analysis operation, along with power supply verification,
ensure the best and most accurate results in dosing operation, frequency or voltage fluctuations.
[TANk LEVEL]
Level probe signals when additive level in the tank is below allowable height. The pump therefore stops. Display will show
[TANk LEVEL]
. Once additive level is restored, message is turned-off and pump will restart.
[DATA ERROR]
It appears every time there has been a mistake in programming. Re-enter the
programming mode
and follow instructions.
[MEM ERROR]
Indicates a problem with microprocessor memory.
For assistance, please contact EMEC service department or any
other authorized personnel.
