5.3.3 Heater Current Parameters
5.3.3.1 HEATER CURRENT HIGH SCALE LIMIT {P} = c
This parameter defines the full scale value for the heater currrent range and may
be modified/interrogated using a Type 3/4 message sequence only. It may be
adjusted from 10.0A to 20.0A in 0.1A increments, and then from 21A to 100A in 1A
increments. The default value is 50A. Heater current range minimum is fixed at
0A.
NOTE: If this parameter value is changed, the Heater Nominal Current, Low
Heater Break Alarm Value and High Heater Break Alarm Value parameters
are set to their default values.
5.3.3.2 HEATER NOMINAL CURRENT {P} = d
This parameter defines a nominal value for the heater current and may be
modified/interrogated using a Type 2 message or a Type 3/4 message sequence.
It may be adjusted in the range 0A to Heater Current High Scale Limit value. The
default value is the Heater Current High Scale Limit value. This parameter is
accessible only if Heater Break Alarm Strategy is set to Percentage Mode.
5.3.3.3 HEATER ACTUAL CURRENT {P} = e
This parameter indicates the most recent valid heater current value at the instant
the message is received; it is equivalent to calling up the heater current display
from the front panel. This parameter may be interrogated only using a Type 2
message.
5.3.4 Setpoint Parameters
5.3.4.1 SETPOINT VALUE {P} = S
This parameter may be modified/interrogated using a Type 2 message or a Type
3/4 message sequence. It can be set to any value between Setpoint High Limit
(see Subsection 5.3.4.3) and Setpoint Low Limit (see Subsection 5.3.4.4).
5.3.4.2 SETPOINT RAMP RATE {P} = ^
This parameter may be modified/interrogated using a Type 2 message or a Type
3/4 message sequence. It defines the rate at which the current setpoint can be
made to ramp and can be set to a value in the range 1 - 9999 increments per
hour. If it is desired to switch setpoint ramping OFF, a Type 3/4 message sequence
should be used in which the {DATA} element of the Type 3 message should be set
to 0000. If setpoint ramping is OFF, the {DATA} element in the response to an
interrogation will be set to 0000. The decimal point position is as for the input
range.
