bAC Er3 Programme module compatibility fault with the base unit dur-
ing the back-up process
The program sequence of the program module is not com-
patible with the base unit
Err PrC Fault with the program module – Error in the data contained in the program module
– No program module
Loc 2 No flame at the end of the safety time – Fuel valves dirty or defective
– Flame detector dirty or defective
– Burner not adjusted correctly, no fuel
– Ignition device defective
Loc 3 Error with air pressure switch (air pressure switch soldered
in position with no load), reduction to specified time (air pres-
sure switch) response time)
Air pressure switch faulty
– Loss of air pressure signal after the specified time
– The air pressure switch is soldered in a position without
load
Loc 4 Extraneous light Burner start-up extraneous light
Loc 5 Air pressure error, air pressure switch soldered in an opera-
tional position
Air pressure switch time out
– The air pressure switch is soldered in an operational posi-
tion
Loc 6 Fault with the actuator – Actuator defective or blocked
– Faulty connection
– Incorrect adjustment
Loc 7 Loss of flame – Too many flame losses during operation (limitation of
repetitions)
– Fuel valves dirty or defective
– Flame detector dirty or defective
– Burner adjustment incorrect
Loc 8 --- Free
Loc 9 --- Free
Loc 10 Non attributable error (application), internal error Wiring error or internal error, outlet contacts, other faults
Loc 12 Valve test Fuel valve 1, leak
Loc 13 Valve test Fuel valve 2, leak
Loc 14 POC error POC error valve closure control
Loc 20 Min gas pressure switch open No gas
Loc 22 Safety loop open – Max gas pressure switch open
– Limit thermostat safety lockout
Loc 60 Analogue power supply source 4...20 mA, I < 4 mA Wire broken
Loc: 83 PWM fan faulty – The PWM fan does not reach the expected speed within
the pre-set period of time, or
– After reaching the expected speed, the PWM fan once
again falls outside the tolerance range (P650) for a peri-
od of time greater than the time admissible for speed de-
viation (P660)
Loc 138 Reset process successful Reset process successful
Loc 139 No program module detected No program module identified
Loc 167 Manual lockout Manual lockout
Loc: 206 AZL2... incompatible Use the latest version
Loc: 225 PWM fan faulty – The fan speed dropped below the PWM pre-purging
maximum (P675.00) after reaching the pre-purging
speed, or
– After reaching the ignition load speed, the PWM maxi-
mum ignition load (P675.01) was exceeded
Loc: 226 PWM fan faulty Configuration error:
– Low flame speed > high flame speed, or
– Low flame = 0 rpm, or
– Maximum speed = 0 rpm
Loc: 227 PWM fan faulty One or more parameters violate the minimum/maximum limit
rSt Er1 Programme module compatibility fault with the base unit dur-
ing the reset process
The sequence of the program module is not compatible with
the base unit
rSt Er2 Programme module compatibility fault with the base unit dur-
ing the reset process
The hardware of the base unit is not compatible with the pro-
gram module
rSt Er3 Error during the reset process – Fault with the program module
– Program module removed during the reset process
