| SERIES HSM SIGNALS AND FLAGS | |||
| Specification | Rating/Description | Condition | |
| Status Flags (1) (Form C dry relay contacts) |
POWER: | Indicates low source voltage; signal asserted 5 milliseconds 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 (1) (front panel LEDs) |
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 operatoe independently although driven by the same detector circuit. |
