shedding parameters (including fail-safe) are configured with default values. The CONSOLE SET-
POINT MAXIMUM
and MINIMUM are also configured with default values.
Procedure: Enter the “Copy Configuration Sub-Menu” and select DEFAULTS TO A.
3.11.3 COPY DEFAULTS TO POINT B (V3.11 AND UP)
Purpose: Loads the point-specific Tyco Thermal Controls default configuration parameters, as
defined in Appendix F, for Point B. As well, all of Point B’s maintenance data are reset. All load-
shedding parameters (including fail safe) are configured with default values. The
CONSOLE SET-
POINT MAXIMUM
and MINIMUM are also configured with default values.
Procedure: Enter the “Copy Configuration Sub-Menu” and select DEFAULTS TO B.
3.11.4 COPY POINT A TO POINT B (V3.11 AND UP)
Purpose: Copies the point-specific configuration parameters of Point A to Point B. Point A’s con-
figuration parameters are not changed.
Procedure: Enter the “Copy Configuration Sub-Menu” and select A TO B.
Notes:
• To ensure that the
TAGs for both points are not the same, Point A’s TAG is copied, the last
character incremented by one, and then written to Point B’s
TAG.
• None of the communications addresses or the maintenance data values are copied.
3.11.5 COPY POINT B TO POINT A (V3.11 AND UP)
Purpose: Copies the point-specific configuration parameters of Point B to Point A. Point B’s con-
figuration parameters are not changed.
Procedure: Enter the “Copy Configuration Sub-Menu” and select B TO A.
Notes:
• To ensure that the
TAGs for both points are not the same, Point B’s TAG is copied, the last
character incremented by one, and then written to Point A’s
TAG.
• None of the communications addresses or the maintenance data values are copied.
Section 4 Monitored Parameters
4.1 Introduction
The following is a brief summary of each of the measured and calculated parameters the 920
series control module provides to the user. Detailed information regarding settings, alarms lim-
its, etc. may be found in Section 3 on page 18. For detailed information regarding the display of
these variables using the 920 operator console or the Model 780/GCC-9000, refer to the appro-
priate user manuals.
4.2 Analog Readings
4.2.1 CONTROL TEMPERATURE
Purpose: This is the temperature the controller uses to determine whether its output switch
should be on or off. Depending on the
TS CONTROL MODE setting, whether one or two RTDs are
installed, and
TEMPBUS™ is being used, the CONTROL TEMPERATURE may be derived from TS 1,
TS 2, TEMPBUS™ or a combination of the three temperatures. See section 3.5.12 on page 24 of
this manual for further details regarding the
TS CONTROL MODE settings.
4.2.2 TS 1 TEMPERATURE
Purpose: This temperature is the value the controller reads from the
RTD connected to its TS 1
input. Depending on the
TS CONTROL MODE, it may be used to determine the CONTROL TEMPERA-
TURE
(see section 4.2.1 on page 47).
