 Relay energized delay and Relay de-energized delay
Settable range: 0.0(s)~9(m)59.9(s)；
This function is primarily to avoid instrument disruption
or instability of input signals and relay misoperation。
● Relay energized delay [ ry_,rd] (Fig.4-): When
the value is reached when the conditions of the
relay, the relaywill delay action until；
EX: Relay 1 setting
[ry!md]: hi；[ry!rd]: )0%0；[ry!sp]: 10)0
When (PV) over 10)1 (PV>[ry!sp])and keep over 5
sec，Relay output will be Action (ON)。
● Relay de-energized delay [ ry_,fd] (Fig.4-):
If the display value to leave therelay of the conditions
and set lasting more than this,the relay will reset
EX: Relay 1set
[ry!md]: hi；[ry!fd]: )0@0；[ry!sp]: 10)0
When (PV) less than 9(9 (PV<[ry!sp]) and keep
over 2 sec，Relay reset(OFF)。

■ Analogue Output Functions
CM1 series offer the 2 relay outputs，Different control
functions can be individually planned its related functions can
be set at the button panel . Details are as follows；
 Relay energized mode [ ry_.md]
selection：Hi / Lo
Hi ( hi) (Fig.1-): Relay will be energized,
when PV > Set Point
Lo ( lo) (Fig.1-): Relay will be energized,
when PV < Set Point

 Start delay band and Start delay time
The functions have Been designed for
1. To avoid starting current of inductive motor (6 times of
rated current) with alarm.。
2. If the ry_.md relay energized mode had been set to
be lo(Lo) or lOhld(Lo & latch). As the meter is
power on and no input to display the "0" caused the
relay will be energized. User can set a band and
delay time to inhibit the energized of relay。
● Start of band of Relay energized [ rYsb] (Fig.2-)
Settable range from 0~9999 Digits；
When displaying the value exceeds started after no
action, and then after startup delay time, the relay
will start the PV value is compared with the set value
output。
● Start band [ rYsd] (Fig.2-)
Settable range: 0.0 Sec~9(m)59.9(s)。

 Hysteresis [ ry_,hy] (Fig.3)
Settable range: 0~5000 Counts；
As the display value is swing near by the set point to
cause the relay on and off frequently. The function is to
avoid the relay on and off frequently such as
compressor…….etc.,
User can set a band to prevent from the relay on and
off frequently。
Please specify the output type either 0~10V or
4(0)~20mA in ordering code. The output low and high
can be programmable which it's related with various
display values. Reverse slope output is decided by
reversing point positions
● Output range selection
Voltage output specified, Programming :
: V0-10(0~10V) / V0-5(0~5V) / V1-5(1~5V)
Currnet output specified Programming :
: A4-20(4~20mA) / A0-20(0~20mA) /A0-10(0~10mA)
 Output signal corresponds to display value
Settable range: -19999~+29999/99999;
Low Output corresponds to Low display value
[ aOls]: Setting the Low Display value versus Low
output range (as like as 4mA in A4-20)。
Analogue Output relative High Scale) [ aOls]: Setting
the High Display value versus High output range (as like
as 20mA in A4-20)
