• Computer Control 
  An RS-232 port is provided to interface with a PC. The ESMH-DC accepts a number of commands pertaining to test stand motion and force gauge functions*. The following additional items are required for PC control: 
  - Series 7/5 force gauge or Model 7i/5i indicator
  - 09-1056 serial cable (see Optional Equipment) 
  - 09-1162 multi-function cable (see Optional Equipment)
• Overload Protection 
  Protects a force or torque gauge against overload. The user programs the desired percentage of full scale of the gauge. Adjustable analog output voltage setting allows the controller to interface with virtually any force or torque gauge with analog output. Requires one of the above mentioned instruments and 09-1162 multi-function cable.
• Auto-return 
  The crosshead moves to a limit switch, force (requires one of the above mentioned instruments and 09-1162 cable), or travel position (TSTM only), stops, and reverses direction at full speed to the other limit switch, force, or travel position.
• Cycling / Dwell 
  Time The crosshead moves up and down between limit switches or force set points (requires a Series 4, 5, or 7 force gauge). Configurable up to 99,999 cycles. Dwell time allows the operator to program the amount of time, up to 9,999.9 seconds, in 0.1 second intervals, for which the crosshead pauses at limits.
• Programmable Button Functions 
  Expands UP and DOWN button operation to three user-configurable modes: 
  1. Maintained (standard): short push produces continuous motion until STOP is pressed 
  2. Momentary: crosshead moves only while the button is pressed 
  3. Auto: short push produces maintained motion, while holding the button down will produce
• Independent Up and Down (CW and CCW) Speeds
  Programmable independent speeds for up and down directions (CW and CCW for torque test stands)
• Selectable speed units of measurement (in/min & mm/min)
• Password protection 
  Prevents unauthorized changes to test parameters
• Broad speed range (see below)

• Speed accuracy: ±0.2% of setting, ±0% variation with load
• CE mark
• Universal power supply: 80-250 VAC
• Mounting holes for bench mounting
