Functions Activated by Digital Inputs

Use digital inputs to activate the following functions:

• Load a job that is stored in controller memory. See

BCD Job Load on page 97.

• Change all loops to manual mode at specified output

levels. See Mode Override on page 99.

• Enable thermocouple short detection. See Thermocou-

ple Short Alarm on page 101.

• Restore automatic control after a failed sensor has been

repaired. See Restore Automatic Mode on page 114.

TB18 Connections

Table 2.5 TB18 Connections

The indicated outputs are dedicated for control when enabled in the

loop setup. If one or both of the outputs are disabled for a loop, then the

corresponding digital outputs become available for alarms or program-

mable logic.

If you install a Watlow Anafaze Serial DAC, the CPC400 series control-

ler uses digital output 34 for a clock line. You cannot use output 34 for

anything else if a Serial DAC is installed.
