Fig. 2 Dimensions of the Panel Cutout
HORIZONTAL MOUNTING: Minimum distance between cutouts: 20 mm
PACKING OF MORE INSTRUMENTS IN A SINGLE CUTOUT (max. 10 instruments): The vertical
dimension of the cutout is the addition of the front dimensions minus 3 mm. Vertical dimension of
the cutout = (n x 48) - 3 mm where n is the number of instruments to be packed.

1.1 INTRODUCTION
The 1400 Series is a family of general purpose digital panel indicators developed with the latest
technology available today and aimed to reduce costs and improve simplicity during installation and
use. As part of the Dynisco background, this family also maintains a high standard in quality,

6
reliability and man/machine interface simplicity.
Features like three independent alarms, alarm masking during start up, manual or automatic alarm
reset, programmable alarm hysteresis, max. measured value data hold, min. measured value data
hold, analog retransmission of the measured value and linear input scaling with programmable
digital filter on the measured value, offer the wide range of possible applications.
The 1400 comes with a complete availability of ranges from thermocouple, RTD, mV, V and mA
input and can also be supplied with three independent alarms.

NOTE: 1) To avoid electric shock, connect power supply at the end of the wiring procedure only.
2) The power supply input has no fuse protection. Please provide it externally.
B) INPUTS
Thermocouple Input
Fig. 7 Thermocouple Input Wiring
NOTE: 1) Don’t run input wires together with power cables. Use proper thermocouple extension
wire cable preferably shielded (see table).
2) If shielded cable is used, the shield must be grounded at one point only.
3) Pay attention to the line resistance; a high line resistance may cause measurement errors
(see Product Specifications).

NOTE: 1) Don’t run input wires together with power cables
2) Use proper cable, preferably shielded
3) Pay attention to the line resistance; a high line resistance may cause measurement
errors.
4) If shielded cable is used, the shield should be grounded at one point only (see Fig. 9)
RTD Input
Fig. 9 RTD Input Wiring
NOTE: 1) Don’t run RTD wires together with power cables
2) If shielded cable is used, the shield must be grounded at one point only
3) Use copper wires with appropriate size (see Product Specifications)
4) The resistance of the 3 wires must be the same
Any external components (like zener barriers etc.) connected between sensor and input terminals
may cause errors in measurement due to excessive and/or not balanced line resistance or possible
leakage currents.
C) ALARM 1 AND ALARM 2 RELAY OUTPUTS
Fig. 10 Alarm 1 Relay Wiring

16
Fig. 11 Alarm 2 Relay Wiring
The relay output is an SPDT relay, without snubber network.
The contact ratings are: 3 A/30 V DC on resistive load or
3 A/250 V AC on resistive load.
The MTBF is 2 x 105at specified rating.
D) ALARM 3 RELAY OUTPUT
Fig. 12 Alarm 3 Relay Wiring
The relay output is an SPST relay, without snubber network.
The contact ratings are: 2 A/30 V DC on resistive load or
2 A/250 V AC on resistive load.
The MTBF is 2 x 105at specified rating.
E) INDUCTIVE LOADS
Switching inductive loads, high voltage transients may occur. These transients may damage the
internal contacts, PCB or affect the performance of the instrument. In this case an external snubber
should be connected across the terminals as near as possible to the terminals (see Fig. 13).

1400/1401 Digital Panel Indicators 17
Fig. 13 External Protection for Inductive Load Greater than 40 mA AC
The value of capacitor (C) and resistor (R) are shown in the following table.
INDUCTIVE C R RESISTOR OPERATING
LOAD (µF) (⍀) POWER (W) VOLTAGE
<40 mA 0.022 100 1/2 260 V AC
<150 mA 0.1 22 2 260 V AC
<0.5 A 0.33 47 2 260 V AC
The same problem may occur when a switch is used in series with the internal contacts as shown in
Fig. 14.
Fig. 14
In this case it should be better to protect the switch also as shown in Fig. 14. Anyway the cable
involved in relay output wiring must be as far away as possible from input or communication cables.

18
F) ANALOG RETRANSMISSION OUTPUT WIRING
For mA output the maximum load is equal to 500 V.
For V output the minimum load is equal to 5 kV.

Indicator OFF = no alarm condition
Indicator ON = alarm condition
Indicator flashing = the alarm condition has disappeared but the instrument is waiting for a
manual reset of the alarm.
PK Indicator OFF = instrument shows the measured value
Indicator ON = instrument shows the “Peak high” value
Indicator flashing = instrument shows “Peak low” value

1400/1401 Digital Panel Indicators 19
3.1.2 DISPLAY
The display continuously shows the measured value in eng. units. During configuration and
calibration set up, this display is used to show parameter’s name and the relative value.
3.1.3 KEYBOARD DESCRIPTION
Increases the parameter value or to display the peak high value.
Decreases the parameter value or to display the peak low value.
Selects all the parameters. By pushing the F button the parameters will be shown
sequentially on the display and, at the same time, the value of the previous parameter will
be stored.
During configuration and calibration procedures and alarm threshold setting, it is used to
scroll back to the parameter without storing a new value.

Used to reset peak high and peak low and restart the peak detection procedure.
Used to start the default parameters loading procedure.
