Millivolt signals are not counted by the PIM unless a suitable preamplifier is used to boost the signal to a level that can be detected by the PIM circuitry. l Current Pedestal signaling is not directly supported by PIM circuitry.
Introduction
As an option, the recorder can support the programming of a 36-segment setpoint program containing 18
ramp segments and 18 soak segments. In a ramp segment the setpoint value is changed as specified during
configuration. The ramp is configured in terms of ramp time or ramp rate, depending on how you have
configured the RAMPUNIT parameter. During a soak segment the setpoint is held at the specified value.
For each control loop you can build up to 6 profiles using any number of consecutive segments of the
program.
Odd-numbered segments are always ramp segments. Even-numbered segments are always soaks. These
ramp and soak segments can be used in up to six programs. You designate the beginning and end segments
to determine where the program will start or stop.
· Every profile must start with a ramp segment and end on a soak segment.
· Control Loop must have Setpoint Source set to 1LOCAL.
· Control Loop 1 uses SP RAMP1, Control Loop 2 uses SP RAMP2. SP RAMP1 and SP RAMP2 are the
prompts under which the setpoint program is configured.
· Recorder must be set to use SP1 (setpoint 1).
· Only contiguous segments can be used by a profile.
· There can be overlap between programs. For example, Profile 1 could use Segments 1, 2, 3, 4, 5, and 6.
Profile 2 could be configured to begin with Segment 5 and end with Segment 8.
This section contains instructions for setting up a setpoint program, and for executing the program at
runtime.
Note that Section 4 contains instructions for using the setpoint ramp or setpoint rate. The SPRAMP
(setpoint ramp) and SPRATE (setpoint rate) parameters described in Section 4 must be set to
DISABL (disabled) if a setpoint program is to be used.
ATTENTION
If power is lost during execution of a program, upon power-up the recorder will use the last
setpoint value prior to the beginning of the setpoint program. The program is placed in hold at
the beginning. The Manual/Auto mode will be as configured under “POWER UP” in the
“CONTROL” group.
