| SERIES KHX SIGNALS AND FLAGS | |||
| Specification | Rating/Description | Condition | |
| Status Flags (Form C dry relay contacts) |
POWER: | Indicates low source voltage;signal asserted 5msec prior to loss of output voltage. | Both NO and NC available |
| OUTPUT: | Indicates normal operation | ||
| OVER TEMP: | Over temperature shutdown | ||
| FAN FAIL: | Failure of internal fan | ||
| Status Indicators Front panel LEDs (1) |
POWER: | Green | Lit when a-c is sufficient |
| DC FAIL: | Red | Lit when output failure is detected | |
| OVER TEMP: | Yellow | Lit when thermostat activates | |
| FAN FAIL: | Red | Lit when fan failure is detected | |
| Test Points | Monitor setpoint voltage | 0.1 x EOUT | |
| Monitor setpoint current | 0 - 5V full scale | ||
| Auxiliary Voltage (isolated) |
4-5 - 5.5V d-c isolated 0 - 100 milliamperes |
Present whenever housekeeping supply is operating | |
| (1) | Status indicators and Status flags are isolated and operate independently although driven by the same detector circuit. |
