Application notes
Intervention Modules
The demand for security apparatus, heating, air conditioning or efficient
energy use in offices, hotels, and private homes or in industrial space
is growing constantly, leading to the installation of increasingly
complex electronic systems. But what happens if these systems
malfunction and a qualified service technician will only be available
in a few hours, or even days?
With the use of carefully installed intervention modules, a trained
caretaker or security guard can be in a position to recognize
interruptions in service, and by manual intervention perform the
necessary override actions to maintain system operation until a repair
can be effected.
Digital Override control module
Auto-Off-On output module (Type 19.21)
Many processes or systems are automatically controlled by an electronic
control system or by a Programmable Logic Controller.
In the event of an electronic system malfunction it is important, in
order to avoid damage or downtime, to plan for the possibility of
controlling the process manually. An Auto-Off-On Module can provide
this, located between the output of the electronic system (Controller) and
the process to be controlled (End Process) - bypassing the malfunctioning
control unit in a planned way. For malfunctioning electronic systems,
the process to be controlled can be manually switched On or Off, as
needed, using the switch on the front of the unit. Under healthy
functioning of the electronic system, the switch is left in the Auto
position. In this configuration the process is controlled by the normal
functioning of the electronic system and its output. It may be important
to know (remotely) if the process is being controlled manually or
automatically, in which case the feedback contact on the Auto–Off–On
module 19.21 can provide this.
Status indicating module (Type 19.31 and 19.32)
These single and dual channel indicating modules provides an imme-
diate visual indication of the status of a controller input or output,
emphasizing its importance or urgency according to the color of the
LED. A change-over output contact which follows the input to the
module is available if further control or where status feedback is required
at another location - such as central control room.
These indicating modules can be used to signal, for example, that a
heating unit is in its summer position and not turned on, or that it is
heating under correctly functioning control etc. The module’s legend plate
clearly identifying the condition being monitored and signaled.
EN 60073 defines the color RED for danger conditions; GREEN for
secure normal operation; and BLUE for a prescribed activity, e.g. fire
or other alarm condition. The LED indicator color being pre-selected
using the switch on the back of the module.
Override Control Modules (Type 19.41 and 19.42) may be installed if,
in the event of a electronic system malfunction, emergency working has
to be restored by means of manual intervention. On notice of a
malfunctioning system, perhaps through a feedback contact from a
Status Indicating Module, the caretaker on-site can then go to control
panel housing the appropriate Override module and respond to the
malfunction by manipulation of the Auto-Off-Hand switch. The 19.41
module has a three-position switch marked A-O-H. A= Automatic
operation, O=OFF and H=Hand (or Manual operation).
Moving away for the Auto position means that the module’s output
relay is no longer under the control of the defective electronic Control
System. Turning the switch to “H” energizes the output relay, whilst
selecting the “O” position ensures the relay is de-energized.
For example: a defective heating control system can be manually
overridden to be On in the “H” position or Off in the “O” position. In
this way heating can be maintained until the faulty controller can be
replaced.
The module’s green LED will indicate that the Heating is On, whilst the
flashing Yellow LED is a reminder that the task is under manual control,
and that on the replacement of the defective electronic control system
the Auto-Off-Hand switch should be returned to the “A” position.
The 19.42 override module is similar in principle to the 19.41
module except that it is intended for use with two-stage operations as
associated with star-delta motor starting, two-speed fan motors, or
forward/reverse motor switching. In these applications it is usually
necessary to incorporate a “dead” time of > 50ms between the two
On states. Consequently, when manually switching with the 19.42,
between the “Low” and “High” state and vice versa, a “dead” time of
> 80ms is provided for, within the module.
Note of caution: Where the reversal of motor direction is achieved by
dual motor windings and a switched capacitor, an interval of
approximately 300 ms should be provided. This will need to be
provided by the inclusion of a separate timer in the control circuitry.
To protect motors with a high moment of inertia (such as large fans and
flywheels); when switching from high speed to lower speed, the
lower speed should only be switched on when the motor has come
nearly to a complete halt.
Analogue Override control module
Analogue output module (0…10)V (Type 19.50)
This module can be installed where there is need to give a manually
adjustable analog signal (0…10)V priority over an analog signal from
a electronic control unit or PLC, or to override and replace a
malfunctioning signal.
The Analogue override module provides, by the selection switch on the
front panel, a (0…10)V output signal either generated automatically
or by hand. With the selector switch in position “A“ (Automatic) the
(0…10)V signal at Yout-A2 is derived from the controller signal applied
to terminals Yin-A2. In position “H” (Hand) the controller signal is
ignored and the (0…10) V signal is derived directly from the
potentiometer setting on the module front panel.
Operation in switch position H is indicated by a blinking yellow LED,
and by the opening of contact 51-52 – which could be used to report
the override condition to the central control room.
