1. General notes
• Disconnect power prior to installation
• Installation only by Qualified personnel
• Follow all applicable local and national electrical codes
• Due to potential hazardous voltages in close proximity, use a nonconductive tool and proper PPE when adjusting the potentiometers
on the front panel.
Please observe that applications with high insulation voltages require
sufficient space or insulation to adjoining devices, as well as protection
against accidental contact. Generally speaking, fer rules with plastic collars
are to be used.
Protective measures must be taken against electrostatic
discharges (ESD) when installing and setting the
931S-V1R1D-MC1R
1.1 Notes on EMC
Deviations may occur during disturbances caused by HF radiation. It is possible to reduce these interferences by installing the
electrical equipment into a shielding enclosure, using shielded
cables or cable filters.

2. Function description
2.1 The 3 Way Monitoring Isolator 931S-V1R1D-MC1R monitors
24Vac/dc to 260Vac/dc voltage in single-phase power supply
systems. This voltage range can be divided into 4 individual ranges.
Power is supplied via the monitoring input. A relay with changeover
contact is used for the switching output. Fundamentally, the device
works on a closed-circuit current principle; that means that the
relay picks up by status OK, and drops out when an alarm is
signalled.The switching point is set via a potentiometer (located
under the front plastic cover).
Functions:
- High Trip: The relay switches when the set operating
point is exceeded
- Low Trip: The relay switches by underflow of the set
operating point
- Memory on: The output alarm status is retained; it can
be reset via an internal pushbutton or
external reset input
- Memory off: The alarm status is not stored
- Hysteresis, small: Pickup and release delay of 5V/8V
depends on the range set
- Hysteresis, large: Pickup and release delay of 10V/16V
depends on the range set
- AC voltage: AC voltage measurement of the input
signal
- DC voltage: DC voltage measurement of the input
signal

3. Configuring the module
3.1 Required tool
A screwdriver with a 2.5-mm blade is required to set the
module and to connect the conductors to the terminals.
3.2 To open the module
Remove the connector. Disengage the locking mechanism by
lightly pressing the locks on both
sides of the housing 햲, remove
the upper part of the housing
and the electronics 햳.
