407
error message E1x061: PGA DAC adj failed (a, b, c)
description Tries to adjust the offset voltage of the PGA
test value a shows the ADC offset reading
b shows the limit for an upper offset
c shows the limit for a lower offset
x refers to the module channel tested
action Please return the unit to your local service center for repair
error message E1x062: PGA gain adj failed (a, b, c)
description Verifies the gain settings of the PGA (x 1/10/100). A voltage of
25 mV is applied to the input of the PGA and then amplified
test value a if 1, the required division has failed
if 0, the calculated factors are correct
b shows the measured values for an amplification by 10
c shows the measured values for an amplification by 100
d shows the quotient of b divided by c
x refers to the module channel tested
action Please return the unit to your local service center for repair
error message E1x063: Lambda DAC adj failed (a, b, c, d)
description Verifies the gain of the responsiveness correction stage
test value a if 1, the quotient d could not be calculated, otherwise 0
b shows the difference between DAC settings 1024 and
2048
c shows the difference between DAC settings 2048 and
4096
d shows the quotient of b divided by c
x refers to the module channel tested
action Please return the unit to your local service center for repair
error message E1x080; TEC settling failed (a, b)
description Verifies the comparator output of the regulation circuit after the
TEC is enabled and expects an ADC reading of about 512
test value a shows the ADC reading of the comparator output
b shows the time when the temperature regulation has
reached the default temperature. Waits maximum 30 sec-
onds
x refers to the module channel tested
action Please return the unit to your local service center for repair
