USE THE STATUS/ENABLE D-SUB

Figure 27. Status/Enable 9-pin D-SUB

REMOTE ENABLE INPUT (PINS 1 & 2)

This is a TTL signal that will override the front panel ENABLE

button. The default polarity is ENABLE HIGH. Enter 0 V to

disable the output regardless of the front panel enable button.

An internal 100 kΩ pull up resistor means no external voltage

is required for front panel operation with the default polarity.

The polarity can be changed by remote command.

ENABLE STATUS (PINS 5 & 6)

This is a TTL signal that goes HI when the output current is

enabled.

AT TEMPERATURE STATUS (PINS 5 & 7)

This is a TTL signal that goes HI when the actual temperature

is within the window defined by setpoint ± tolerance.

FAN CURRENT DRIVE (PINS 8 & 9)

This output will drive 12 V up to 0.5 A to power a fan for airflow

across the thermoelectric and load. The auxiliary thermistor

can monitor the temperature of the load heatsink.

CHANGE FUSES

Figure 28. Fuse Box

1. On the back panel (see

page 9), locate the Fuse Box.

2. Insert a small flathead screwdriver into the slot (1) at the

top of the box and twist to open faceplate.

3. Install the fuses, one on each side of the receptacle,

as shown in the image below, making sure the fuses

contact the metal plate at the connector end of the fuse

receptacle.
