1. A monitoring module to determine a status of an array of electrical components, comprising:
- a resistance measurer to measure a resistance of the array of electric components connected in parallel across a pair of diagnostic terminals;
a comparator to compare the measured resistance with a set of reference resistances; and
a status module to identify, based on the comparing, which electrical component in the array of electrical components has been disconnected, the status module to identify a first electrical component in the array of electrical components as disconnected in response to the measured resistance matching a first reference resistance of the set of reference resistances, and to identify a second electrical component in the array of electrical components as disconnected in response to the measured resistance matching a second reference resistance of the set of reference resistances.

Abstract
According to one example, there is provided a monitoring module for determining the status of electrical components in an array of N electrical components. The monitoring module comprises a resistance measurer to measure the resistance across a pair of diagnostic terminals, a comparator to compare the measured resistance with a set of reference resistances, and a status module to determine the status of at least one electrical component in the array based on the comparison.

10. A printer having an array of fans including respective diagnostic modules, comprising:
a monitoring module to; measure a parallel resistance of the diagnostic modules connected in parallel across a pair of diagnostic lines; compare the measured parallel resistance to a set of reference resistances; and based on the comparing, identify which fan of the array of fans is disconnected, the monitoring module to identify a first fan in the array as disconnected in response to the measured parallel resistance matching a first reference resistance of the set of reference resistances, and to identify a second fan in the array as disconnected in response to the measured parallel resistance matching a second reference resistance of the set of reference resistances. - View Dependent Claims (11, 12, 13, 14)

15. A method of determining a status of an array of electrical components, each respective electrical component having a diagnostic module exhibiting a first resistance when the respective electrical component is operating correctly, and a second resistance when the respective electrical component is not operating correctly, the method comprising:
-
measuring a parallel resistance of the diagnostic modules connected in parallel across a pair of diagnostic lines; determining that all of the electrical components are operating correctly in response to the measured parallel resistance being substantially equal to a first reference resistance; determining that one of the electrical components has failed in response to the measured resistance being substantially equal to a second reference resistance; and identifying which of the electrical components in the array is disconnected based on comparing the measured parallel resistance to a set of reference resistances, wherein the identifying identifies a first electrical component in the array as disconnected in response to the measured parallel resistance matching a third reference resistance of the set of reference resistances, and to identify a second electrical component in the array as disconnected in response to the measured parallel resistance matching a fourth reference resistance of the set of reference resistances. - View Dependent Claims (16, 17)
