OMEGA Model CYD201/CYD208 User’s Manual
Operation 3-3
2. Hold UNITS until the desired temperature displays. UNITS is a toggle; if
it is released and pressed again, the temperature direction reverses. If
the temperature display increases, the alarm is a high setpoint. If the
temperature display decreases, the alarm is a low setpoint.
3. Release UNITS when the desired setpoint displays. For a Model
CYD208, press CHANNEL to display the desired channel in the channel
window and repeat the steps above to set the alarm for each channel
4. Move the SET switch back to position 0 to enable the alarm. When it
triggers, an alarm status light appears in the upper left of the
temperature display.
The alarm can be connected to another device which triggers when the
alarm activates. The 3-contact terminal block is present on the rear panel as
J3 ALARM. The alarm contacts are designated 1 COM 2 with 1 representing
the normally open state and 2 representing the normally closed state.
3.5.2 Latched And Unlatched Alarms
Alarms are either latched or unlatched. The alarm is latched when the
LATCH switch is in position 1: the alarm turns On when triggered by the
alarm setpoint, but will
not automatically turn Off when the temperature
returns to within the high and low setpoint range. The alarm is unlatched
when the LATCH switch is in position 0; the alarm turns On when triggered
by the alarm setpoint, and automatically turns Off when temperatures return
to within the high and low setpoint range.
3.5.3 Alarm Fix Function (Model CYD208 Only)
Set the FIX switch on the Model CYD208 rear panel to OFF (position 0) to
continuously update the alarm relay, depending on the alarm setpoint and
sensor temperature. If the FIX switch is ON (position 1), the relay updates
only when channel 1 input is active.
3.6 SOFTCAL™ COMPENSATIONS
SoftCal™ is a simple, instrument-configured software calibration that
improves system accuracy over a specified temperature range. It reduces
the error between a CY-7 diode and the Standard Curve 10 used by the
instrument. In short, SoftCal™ generates inexpensive calibrations for CY-7
sensors used with OMEGA temperature controllers and monitors.
