Fault Codes - Schulz Control I Manual De Instrucciones

Make sure the RS485 cable is fastened and secure.
Handle the equipment with care.
Multi485 protocol:
The port uses a protocol named Multi485, which enables the connection to several compressor management, remote monitoring, and
control option devices, or the connection to a MODBUS RTU network using a MODBUS gateway.

FAULT CODES

5. Fault Codes
The fault codes are divided into two categories:
A: Alarms – illustrated by the symbol at the left; the compressor will keep working if an alarm sounds.
A: 2050 C5 (if the input is configured for alarm).
A: 2060 C6 (if the input is configured for alarm).
A:2118 High pressure: limit exceeded.
A: 2128 High temperature: limit exceeded.
A: 2816 Voltage drop detected.
A: 3123 Start halted: the temperature is below the minimum temperature.
(It will be automatically reset when the temperature is above the set value. It cannot be reset manually).
A: 3423 Load halted: the temperature is below the minimum temperature.
(It will be automatically reset when the temperature is above the set value. It cannot be reset manually).
A: 4804 Air filter exchange- the air filter hour meter reached zero.
A: 4814 Oil filter exchange – the oil filter hour meter reached zero.
A: 4824 Check separation element – the separation element hour meter reached zero.
A: 4834 Exchange oil – the oil exchange hour meter reached zero.
E: Error – The symbol will blink – the compressor will shut down.
E: 0010 Emergency stop – 24 Vac is not being detected in the R1C terminal.
E:0020 C2 – main motor overload
E:0030 C3 – phase lack or incorrect phase sequence
E:0040 C4 – fan motor overload
E:0050 C5 – drier fault
E:0060 C6 – external error
E:0115 Pressure sensor fault: signal outside the range (< 3.8mA or > 20.8 mA)
E: 0019 Overpressure
E:0125 Temperature sensor fault: signal outside the range (< -50°C or > 250°C)
E: 0029 Overheat
