2.8 INITIAL SETUP AND CHECKOUT PROCEDURE
This procedure verifies basic unit operation.
1. Verify proper wall-mount power supply is used. A wall-mounted power
supply is available that accommodates 90-130 VAC or 200-250 VAC
operation. The Model CYD201 requires a 24 Volt input.
CAUTION: Connect temperature sensor(s) to unit rear before applying
power. Sensor damage may occur if connected with power on.
2. Install temperature sensor(s) per recommendations in Paragraph 2.4.
Route wiring to Model CYD201.
3. Connect power plug to 24 Volt receptacle at unit rear, then plug wall-
mounted power supply into power connection.
4. Upon power up, the unit displays the following codes:
“CUO” = CY7
5. If sensor connections are correct and exhibit no opens or shorts, the
temperature displays and the decimal point blinks. (The rate of the
blinking corresponds to the update cycle.)
Sensor connection problems cause one of two messages display:
“OPEN” = Sensor connection loose, polarity backward, or not
connected.
“SHORT” = Wiring is shorted at some point between unit and sensor.
Upon successful completion of this abbreviated checkout procedure,
the unit is ready for normal operation.
