5) SP OUT OF RANGE
Cause: For a two pots closed control loop only. This alarm is the same as
the previous but for the command pot.
Remedy: Check the set point pots connections.
11.1.4 Four blinks alarms
1) EEPROM KO
Cause: It occurs due to a hardware or software defect of the non-volatile on-
board memory parameters.
Remedy: Execute a CLEAR EEPROM operation. To do it Enter the ALARM
CONFIG MENU. Push at the same time the two right side buttons.
This sequence will enter the hidden ZAPI MENU. Roll up and down
(buttons 1 and 2) until the "CLEAR EEPROM" appears on the hand
set display. Push twice the Enter button. If the alarm occurs
permanently, it is necessary to substitute the logic.
Note: each time the Eprom release is changed this alarm could
occur. So we suggest doing a CLEAR EEPROM before changing the
Eprom.
2) GAIN EEPROM KO
Cause: It occurs at startup if some reserved EEprom cells are damaged, or
when substituting an old software (prior than 0.67) with a new one.
Remedy: It is necessary to modify the contents of EEprom address 0 x 63 and
then to clear the EEprom. Ask for Zapi technicians support.
11.1.5 Five blinks alarms
1) HIGH TEMPERATURE
Cause: It occurs if the power base exceeds 76°C.
Remedy: Let the unit cool down. If the alarm occurs after, it is necessary to
improve the unit's heat dissipation capability.
