CAUTION
Controller Mounting Precautions
Keep the input circuit wiring as far as possible away from power and ground circuits.
Keep the units in 10 to 50ºC (50 to 110ºF) with 20% to 90% relative humidity (RH).
The controller may need a warm up period to return to operating temperature ranges when below 10ºC.
To prevent electric shock, be sure to turn off the power source and circuit breaker before wiring.
The power requirements are 100 to 240 VAC, 50/60 Hz, 10 VA max. Do not switch power
supplies without first disconnecting the power supply.
Follow the operating procedures and precautions in the manual to avoid fire, shock, damage to the unit,
or injury. Follow the operations and mounting directions indicated in this manual.
Always create a ground connection where indicated, however do not ground to gas pipes,
water pipes, lightening rods, or other potentially hazardous metal objects.
Do not apply power to the unit until all connections have been made.
Do not cover the venting holes in the rear of the unit.
!
CAUTION
Operational Environment Precautions
(1) Only operate the controller when it is properly installed.
(2) When installing the controller, select a location where:
Rear terminals are protected from accidental contact.
Mechanical vibrations are minimal.
No corrosive gas is present.
Temperature fluctuation is minimal.
Temperature can be maintained between 10 and 50 ºC (50 and 110ºF) with 20 to 90% RH.
No direct heat radiation is present.
High levels of electromagnetic interference are not present
The unit is not exposed to water.
No flammable materials are present.
Dust particles are not present in the air.
Exposure to ultraviolet rays is minimal.
Openings on the rear of the controller are not blocked.
(3) This unit is suitable for installation in an enviornment classified as Pollution Degree 2.
(4) This unit is designated as Installation Category II.
(5) If the equipment is used in a manner not specified by the manufacturer, the protection provided by
the equipment may be impaired.
(6) A switch or circuit-breaker acting as the disconnect device shall be included in the application or the
installation.

This parameter sets the display temperature unit for ºC or ºF.
Its default selection is ºC.
Refer to Table 1 when changing the temperature unit for the temperature input range.
This parameter sets the high limit of the temperature display range (maximum temperature
displayed). For mV and V inputs, this sets the value of the high input of the input scale
defined in In.SH.
This parameter sets the low limit of the temperature display range (minimum temperature
displayed). For mV and V inputs, this sets the low input of the input scale defined in In.SL.
This parameter sets the position of the decimal point for mV or V inputs. The position of
the decimal point can be set as 9999, 999.9, 99.99, or 9.999. Its default set value is 1.
This parameter sets the high limit of the mV or V display scale. This value will be
displayed when the input is set to the high input established in In.rH.
Its default value is 100.0.
This parameter sets the low limit of the mV or V display scale. This value will be displayed
when the input is set to the low input established in In.rL.
Its default value is 0.0.
This parameter sets the PV filter for stabilization from electromagnetic noise and
interference. This will effect the rate of change of the PV display value. Its default setting
is OFF, and can be set from 1 to 120 seconds.
This parameter to establishes PV behavior when an open input sensor is detected. When
BSL is set to UP, the PV operates as if at the high input range. When BSL is set to
DOWN, the PV operates as if at the low input range. Its default setting is UP. In the case
of mV or V inputs, the default setting is OFF. An open sensor check is not performed in 10
V, 20 mV, or 100 mV input settings.
PV
This parameter determines if RJC for thermocouple inputs is used. RJC can be turned
on or off. Its default setting is ON.
This parameter sets where the PV bias points occur. See Fig 1 and Fig 2 for further
information about input bias operation.
This parameter sets the bias value at the corresponding bias point input values. These
parameters establish the value of the offset at each of the defined BSP1 - BSP3 points.
See Fig 1 and Fig 2 for further information about input bias operation.

There are two types of engineering units values used in the setting of parameters, absolute
engineering units (AEU) and general engineering units (GEU). An AEU parameter is set using an
absolute value engineering unit that represents a specific point, such as a specific temperature or
voltage level. An GEU parameter is set using engineering units, however it is a general value, and not
tied to any input or output level.
For example: When establishing input bias, parameter BSP1 sets the specific PV value where bias
point one will occur. This parameter has a unit designation of AEU. BS1, the amount of offset at BSP1
is set in engineering units, however this parameter occurs at whatever BSP1 is set to, and therefore
does not have an absolute setting related to any input or output, it is just the amount of offset at where
BSP1 occurs. While one is related to an absolute input value, and the other stand alone value, both are
set as engineering units, such as BSP1 set as 100ºC and BS1 set as 3ºC.

PV
This parameter establishes reverse (REV) or forward (FWD) activation of the control
outputs. In forward operation, the control outputs will be most active when the PV value is
higher than the SP, as the controller acts to lower the PV. In reverse operation, the control
outputs will be most active when the PV value is lower than the SP value, as the controller
acts to increase the PV. The default setting is REV.
This parameter sets a high limit for the levels of the control output. This limits the output
levels based on a percentage of their full scale. Its default setting is 100 (%).
This parameter sets hysteresis in case of On/Off control output mode in a H/C model.
PV
This parameter establishes the cycle time for use with time-proportional PID relay or
voltage pulse control when the outputs are set to HEAT or COOL. The cycle time can be
set from 1 to 300 seconds. Its default setting is 2 seconds.
PV
PV
This parameter sets a low limit for the levels of the control output. This prevents the
outputs from dropping below a certain level based on a percentage of their full scale. Its
default setting is 0 (%). The outputs are limited by both the the low and high limits.
PV
This parameter establishes the cycle time for cooling outputs if cooling (COOL) control is
set up with time-proportional PID control in a H/C model. (Example: OUT1 = Cool, OUT2
or Out3 = Cool and set to SSR, SUB1 or SUB2 = Cool) The cycle time can be set from 1
to 300 seconds. Its default setting is 2 seconds.
PV
This parameter sets the hysteresis high limit for on/off relay control mode in normal
models (non-Heating/Cooling models).

(non-Heating/Cooling models).
