7.7 I/O CYCLE (INPUTS AND OUTPUTS)
I o 1 I/O 1 FUNCTION: Selects the I/O function to be used
at I/O 1 (relay 1). Options 0 to 5 are possible for this
output. It is normally used as option 5, PWM main
control output. Refer to Table 2 for functions.
I
o 2 I/O 2 FUNCTION: Selects the I/O function to be used
at I/O 2 (relay 2). Options 0 to 5 are available. This
output is normally used as alarm output. See Table 2
for functions.
I
o 3 I/O 3 FUNCTION: Selects the I/O function to be used
at I/O 3 (option 1). I/O 3 can be a relay output or a
digital input/output. Functions 0 to 10 are available.
Refer to Table 2 for functions. The presence of this
I/O option is detected by the controller and the
prompt menu will only be shown if the expansion
option is available.
I
o 4 I/O 4 FUNCTION: Selects the I/O function to be used
at I/O 4 (option 2). I/O 4 can be a digital input/output.
Functions 0 to 10 are available. Refer to Table 2 for
functions. The prompt menu will only be shown if the
expansion option is present.
I
o 5 I/O 5 FUNCTION: Selects the I/O function to be used
at I/O 5 (Analog Output). Functions 0 to 15 are
available (See Table 2). This option is normally used
for main control output or PV analog retransmission.
7.8 CALIBRATION CYCLE
All input and output types are factory calibrated. This cycle
should only be accessed by experienced personnel. If in doubt
do not press the
or keys in this cycle.
Inl( INPUT LOW CALIBRATION: Sets the Process
Variable low calibration (offset). Several keystrokes
at
or might be necessary to increment one
digit.
Inx( INPUT HIGH CALIBRATION: Sets the Process
Variable span calibration (gain).
ovll OUTPUT LOW CALIBRATION: Sets the analog
current output low calibration (offset).
Ovx( OUTPUT HIGH CALIBRATION: Sets the analog
current output span calibration (gain).
(j l COLD JUNCTION OFFSET CALIBRATION: Sets the
cold junction offset calibration.
xtyp HARDWARE TYPE: Configures the controller to
recognize the actual installed optional hardware
(accessories). The parameters menu will show the
parameters relative to the optional hardware:
0 - no optionals or c/ RS485 only
1 - relay 3 (I/O 3)
2 - Digital I/O (2 inputs/outputs)
3 - Heater break protection (option).
Rsl( REMOTE SET POINT LOW CALIBRATION: Sets the
Remote Set Point low calibration (offset). Several
keystrokes at
or might be necessary to
increment one digit.
Rsx( REMOTE SET POINT HIGH CALIBRATION: Sets
the Remote Set Point span calibration (gain).
8 CONTROL # 2
The N1100HC incorporates a second control output with proportional
action. This second control output is intended primarily for
refrigeration, since the control #1 is normally used for heating.
The Control #2 cycle of parameters is listed in 7.3 above.
If the application requires both heat and cool outputs, configure the
parameters ACt
ACt ACt ACt=re re re re e ACt2 ACt2 ACt2 ACt2=dir dir dir dir and set the overlap (OLAP OLAP OLAP OLAP)
accordingl, as follows.
1) OLAP OLAP OLAP OLAP > 0; both outputs may be delivering power to the system.

Output 2 has independent proportional band and PWM period, as
well as maximum and minimum limits for the output.
If Pb2=0, the control #2 becomes ON-OFF, and the OLAP parameter
becomes the Hysteresis for the control #2.

9 RAMP AND SOAK PROFILE PROGRAM
Seven ramp and soak profiles with up to 7 segments each can be
programmed. Longer profiles of up to 49 segments can be created by
linking 2 or more profiles.
