• Excessive heat accumulation.
2.2 Mounting Cautions
Take the following points into consideration when mounting this
instrument in the panel.
• Provide adequate ventilation space so that heat does not build
up.
• Do not mount this instrument directly above equipment that
generates large amount of heat (heaters, transformers, semiconductor functional devices, large-wattage resistors).
• If the ambient temperature rises above 50 °C, cool this
instrument with a forced air fan, cooler, or the like. However,
do not allow cooled air to blow this instrument directly.
• In order to improve safety and the immunity to withstand noise,
mount this instrument as far away as possible from high
voltage equipment, power lines, and rotating machinery.
High voltage equipment: Do not mount within the same panel.
Power lines:
Separate at least 200 mm.
Rotating machinery:
Separate as far as possible.
• Mount this instrument in the horizontal direction for panel. If
you did installation except a horizontal direction, this causes
malfunction.

For mounting of the MA900/MA901, panel thickness must be between 1 to
10 mm. When mounting multiple MA900/MA901s close together, the panel
strength should be checked to ensure proper support.
If the MA900/MA901s have waterproof/dustproof options, protection will be
compromised and not meet IP65 by close mounting.
2.4 Mounting Procedures
When the instrument is mounted, always secure with two
mounting brackets either top and bottom.
The waterproof/dustproof option on the front of the
instrument conforms to IP65 when mounted on the panel.
For effective waterproof/dustproof, the gasket must be
securely placed between instrument and panel without
any gap. If gasket is damaged, please contact RKC sales
office or the agent.
!"Mounting to the panel
1. Prepare the panel cutout as specified in 2.3 Dimensions.
2. Insert the instrument through the panel cutout.
3. Insert the mounting bracket into the mounting groove of the
instrument . (Fig.1)
4. Push the mounting bracket forward until the bracket is firmly
secured to the panel. (Fig.2)
5. The other mounting bracket should be installed the same
way described in 3.and 4.

3. WIRING
This chapter describes wiring cautions and terminal configuration.
"
"
!
WARNING
To prevent electric shock or instrument failure, do not turn on the power until all the wiring is completed.
3.1 Wiring Cautions
For thermocouple input, use the appropriate compensation wire.
#"
For RTD input, use low resistance lead wire with no difference in resistance between the three lead wires.
#"
To avoid noise induction, keep input signal wire away from instrument power line, load lines and power lines of other electric
#"
equipment.
If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.
#"
- Shorten the distance between the twisted power supply wire pitches to achieve the most effective noise reduction.
- Always install the noise filter on a grounded panel. Minimize the wiring distance between the noise filter output and the instrument
power supply terminals to achieve the most effective noise reduction.
- Do not connect fuses or switches to the noise filter output wiring as this will reduce the effectiveness of the noise filter.
About four seconds are required as preparation time for contact output every time the instrument is turned on. Use a delay relay
#"
when the output line is used for an external interlock circuit.
Power supply wiring must be twisted and have a low voltage drop.
#"
For an instrument with 24 V power supply, supply power from a SELV circuit.
#"
This instrument is not furnished with a power supply switch or fuse. Therefore, if a fuse or power supply switch is required, install
#"
close to the instrument.
Recommended fuse rating: Rated voltage 250 V, Rated current 1 A
Use the solderless terminal appropriate to the screw size.
#"
Screw size: M3×6
Fuse type: Time-lag fuse
Recommended tightening torque: 0.4 N・m (4 kgf・cm)

other than the key operation. The memory area transfer by
contact input and the key operation is shown in the following.
When the memory area is transferred by communication, see
the Communication Instruction Manual (IMR01H02-E!).
The AT function automatically measures, computes and sets the
optimum PID and LBA constants. If the AT function is activated,
the optimum PID constants concerning the set value (SV) in the
control area and the LBA setting time can be automatically set
(Limit cycle system is adopted). This function is activated powerON, during temperature rise and/or when control is stabilized from
any process state. The result obtained by AT is reflected to the
parameters (P, I, D and LBA) of the parameter setting mode.

7. FUNCTIONS
This chapter describes an outline of function of MA900/MA901.
7.1 PV Bias Function
7.5 Scan Display Function
The value set in the PV bias is added to the input value (actual
measured value) to correct the input value. The PV bias is used
to correct the individual variations in the sensors or when there
is difference between the measured values (PV) of other
instruments.
The scan display function is for automatically selecting the
PV/SV monitor at the scan interval time for the measured values
(PV) and set values (SV) corresponding to all of the channels
within the control area. This function enables the control trend of
each channel to be checked.
• The transfer speed of the scan display is set with the interval
time of setup setting mode (P. 9).
5.4 Setup Setting Mode (P. 8)
• Use the CH key to stop or start of the scan display function.
The CH key operation is as follows.
7.2 Digital Filter Function
This is a software filter which reduces input value variations
caused by noise. If the time constant of this filter is set
appropriately to match the characteristics of the controlled
object and the noise level, the effects of input noise can be
suppressed. However, if the time constant is too small, the filter
may not be effective, while if the time constant is too large, then
the input response may actually deteriorate.
Press the CH key for 2 sec
Scan start.
Press the CH key
Scan stop.
The channel number can be
changed like 1→2→3→4→1・・・
during scan stopping.*
* In case of MA901:
1→2→3→4→5→6→7→8→1・・・
5.4 Setup Setting Mode (P. 8)
7.3 Multi-Memory Area Function
This function is to store the parameters such as temperature set
value (SV), etc. in up to 8 memories. The parameters which can
be stored as one of memories are set value (SV), alarm 1, alarm
2, alarm 3, proportional band, integral time, derivative time, antireset windup, cool-side proportional band, overlap/deadband,
setting change rate limiter and use/unused of channels. The
parameters stored in one of 8 memories retrieved at necessity
and used for control. The memory area used for this control is
called the control area.

7.6 Batch Setting Function
"#Alarm differential gap
The batch setting function enables the setting of the parameters
selected within one memory area simultaneously to the same
value for all of the channels. The set values (SV) as well as the
parameters set for each channel can be simultaneously set.
If measured value (PV) is close to the alarm set value, the alarm
relay contact may repeatedly turn on and off due to input
fluctuations. By the differential gap, repeated turning ON and
OFF of the relay contact can be prevented.

Alarm is issued when the input value of the current transformer
is below the heater break alarm set value with the control output
turned on. However, no alarm may be normally issued when the
control output is turned on for less than 2 seconds.
When heater current goes following (welded relay contact,
etc.):
Alarm is issued when the input value of the current transformer
is above the heater break alarm set value with the control output

7.9 Control Loop Break Alarm (LBA) Function
The control loop break alarm (LBA) function is used to detect a
load (heater) break or a failure in the external actuator (magnet
relay, etc.), or a failure in the control loop caused by an input
(sensor) break. The LBA function is activated when PID
computed value (output ON time/cycle) falls below 0 % or
exceeds 100 %. The time required for the LBA output to turn on
includes both the time from the initial occurrence of loop failure
and the LBA setting time.

"#Cautions for LBA
• When AT function is turned on, the LBA function can not be
activated.
• No LBA function can be used at heat/cool PID action.
• If LBA setting time does not match the controlled object
requirements, the LBA setting time should be lengthened.
If setting time is not correct, the LBA will malfunction by
turning on or off at inappropriate times or not turning on at all.
• The LBA output is turned off when any of the following cases
occurs with the LBA output turned on.
- When the measured value (PV) rises beyond (or falls below)
the LBA triggering width within the LBA setting time
- When the measured value (PV) is within the LBD
7.10 Set Data Lock Function
The set data lock function permits locking of critical parameters
and prevents unauthorized personnel from changing parameters.
This instrument has the following two lock levels. The two lock
levels can be changed even when the whole set data is locked.
• Lock level to restrict parameter setting changes by key
operation (Lock level 1)
• Lock level to restrict RUN/STOP and memory area changes
(Lock level 2)
