Description
1
Remote
Temperature
Setting
Input
0–10V
• Analog input for temperature adjustment
• 0–100° C (no cooling possible)
• 1 volt = 10° C
• Input impedance 40 KΩ
2
Analog Ground
Ground for temperature adjustment
3
USET (Voltage
Initiate)
Input
0–24V
• Programmed dispensing parameters start (must be a clean,
bounce-free signal)
• Input impedance 1.3 KΩ
NOTES:
• In the Continuous mode, dispensing occurs when this signal is
ON; the controller also executes the values entered for PULSE
(valve open time) and CYCLE (time between deposits).
• In the Timed mode, when this signal rises the controller
actuates the number of deposits entered for COUNT while
also executing the values entered for CYCLE (time between
deposits) and PULSE (valve open time).
• In the External mode, any values entered for CYCLE and
PULSE are ignored and, when this signal rises, one dispense
cycle occurs. This allows precise control of each deposit.

GND
Ground for inputs and outputs

Status of
Temperature
Output
0–24V
Status of output temperature, comparison of actual and target
temperature:
• 0V = Target temperature not reached
• 24V= Target temperature reached (temperature within 6° C)
NOTE:
Use the remote communication capability to change the
target temperature window. Refer to the "trng" command in the
"Temperature" table in “Appendix A, Remotely Operating the
Controller” on page 60.
