Section 1: Optional Module 1:
Modulating I/O Module
1.1 OM1 Module Functionality
The OM1 Modulating I/O module is supplied as an option on Keystone EPI2 actuators.
It is possible to receive the actuator already equipped with the OM1, ordering it with
the basic feature.
Alternatively, it is possible to order the OM1 as a separate kit and install it in the basic
actuator in the factory or in the field.
The OM1 is an optional module suitable to accomplish the following EPI2 actuator
additional functionalities:
June 2022
• Positioner with analog position input 4 - 20 mA or 0 - 10 V DC optocoupled
• Analog output position transmitter 4 - 20 mA or 0 - 10 V DC optocoupled
• Monitor relay remote indication for:
— loss of power
— stop by torque out of limit
— direction failure
— over-temperature
— position sensor alarm
— valve jammed
— hardware malfunction
— alarm on local control panel (if present)
— stroke failure
• Blinker/Local selector relay remote indication
• 4 additional SPST output contacts to be set independently at 12.5% intervals along
the stroke. Contacts are congurable (make or break)
• Optional Bluetooth connection feature
NOTE:
For decommissioning instructions, please refer to the relevant section in the EPI2 manual
ref. VCIOM-15516-EN.

WARNING
!
EPI2 actuator must be electrically isolated before any disassembling or reassembling
operations. Before any disassembling or reassembling operations, please follow in
detail the relevant paragraph of the basic installation and operating manual (latest
revision available).
WARNING
!
The electronic parts of the EPI2 actuators and all option modules can be damaged by
a discharge of static electricity. Before you start, touch a grounded metal surface to
discharge any static electricity.
WARNING
!
It is assumed that the installation, conguration, commissioning, maintenance, and repair
works are carried out by qualied personnel and checked by responsible specialists.

Section 2: Installation
To assemble the OM1 into the EPI2 actuator, proceed as follows:
• Ensure that all the parts received with the OM1 are available as described in
Section 5.
• Using Section 5, select only mechanical parts (screws and spacers) depending on
actuator models.
• Gather the right tools for the assembly and for setting the actuator controls.
• With an Allen wrench of 5 mm, unscrew the cover screws as shown in Figure 1.
• Remove the actuator cover as shown in Figure 2.
